* @tx_ttl_frms: Count of successfully transmitted MAC frames
* @tx_ttl_octets: Count of total octets of transmitted frames, not including

* total octets of transmitted frames, including framing characters,
* multiply PORTn_TX_TTL_FRMS by 8 and add it to this stat (unless
* otherwise configured, this stat only counts frames that have
* 8 bytes of preamble for each frame). This stat can be configured
* (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count everything
* including the preamble octets.
* @tx_data_octets: Count of data and padding octets of successfully transmitted
* frames.
* @tx_mcast_frms: Count of successfully transmitted frames to a group address
* other than the broadcast address.
* @tx_bcast_frms: Count of successfully transmitted frames to the broadcast
* group address.
* @tx_ucast_frms: Count of transmitted frames containing a unicast address.
* Includes discarded frames that are not sent to the network.
* @tx_tagged_frms: Count of transmitted frames containing a VLAN tag.
* @tx_vld_ip: Count of transmitted IP datagrams that are passed to the network.
* @tx_vld_ip_octets: Count of total octets of transmitted IP datagrams that
* are passed to the network.
* @tx_icmp: Count of transmitted ICMP messages. Includes messages not sent
* due to problems within ICMP.
* @tx_tcp: Count of transmitted TCP segments. Does not include segments
* containing retransmitted octets.
* @tx_rst_tcp: Count of transmitted TCP segments containing the RST flag.
* @tx_udp: Count of transmitted UDP datagrams.
* @tx_parse_error: Increments when the TPA is unable to parse a packet. This
* generally occurs when a packet is corrupt somehow, including
* packets that have IP version mismatches, invalid Layer 2 control
* fields, etc. L3/L4 checksums are not offloaded, but the packet
* is still be transmitted.
* @tx_unknown_protocol: Increments when the TPA encounters an unknown
* protocol, such as a new IPv6 extension header, or an unsupported
* Routing Type. The packet still has a checksum calculated but it
* may be incorrect.
* @tx_pause_ctrl_frms: Count of MAC PAUSE control frames that are transmitted.
* Since, the only control frames supported by this device are
* PAUSE frames, this register is a count of all transmitted MAC
* control frames.
* @tx_marker_pdu_frms: Count of Marker PDUs transmitted
* on this Aggregation port.
* @tx_lacpdu_frms: Count of LACPDUs transmitted on this Aggregation port.
* @tx_drop_ip: Count of transmitted IP datagrams that could not be passed to
* the network. Increments because of:
* 1) An internal processing error
* (such as an uncorrectable ECC error). 2) A frame parsing error
* during IP checksum calculation.
* @tx_marker_resp_pdu_frms: Count of Marker Response PDUs transmitted on this
* Aggregation port.
* @tx_xgmii_char2_match: Maintains a count of the number of transmitted XGMII
* characters that match a pattern that is programmable through
* register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
* is set to /T/ (i.e. the terminate character), thus the statistic
* tracks the number of transmitted Terminate characters.
* @tx_xgmii_char1_match: Maintains a count of the number of transmitted XGMII
* characters that match a pattern that is programmable through
* register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
* is set to /S/ (i.e. the start character),
* thus the statistic tracks
* the number of transmitted Start characters.
* @tx_xgmii_column2_match: Maintains a count of the number of transmitted XGMII
* columns that match a pattern that is programmable through register
* XMAC_STATS_TX_XGMII_COLUMN2_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns transmitted at
* any time. If XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is
* set to 1, then this stat increments when COLUMN2 is found within
* 'n' clocks after COLUMN1. Here, 'n' is defined by
* XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set
* to 0, then it means to search anywhere for COLUMN2).
* @tx_xgmii_column1_match: Maintains a count of the number of transmitted XGMII
* columns that match a pattern that is programmable through register
* XMAC_STATS_TX_XGMII_COLUMN1_PORTn. By default, the pattern is set
* to 4 x /I/ (i.e. a column containing all idle characters),
* thus the statistic tracks the number of transmitted Idle columns.
* @tx_any_err_frms: Count of transmitted frames containing any error that
* prevents them from being passed to the network. Increments if
* there is an ECC while reading the frame out of the transmit
* buffer. Also increments if the transmit protocol assist (TPA)
* block determines that the frame should not be sent.
* @tx_drop_frms: Count of frames that could not be sent for no other reason
* than internal MAC processing. Increments once whenever the
* transmit buffer is flushed (due to an ECC error on a memory
* descriptor).
* @rx_ttl_frms: Count of total received MAC frames, including frames received
* with frame-too-long, FCS, or length errors. This stat can be
* configured (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count
* everything, even "frames" as small one byte of preamble.
* @rx_vld_frms: Count of successfully received MAC frames. Does not include
* frames received with frame-too-long, FCS, or length errors.
* @rx_offload_frms: Count of offloaded received frames that are passed to
* the host.
* @rx_ttl_octets: Count of total octets of received frames, not including
* framing characters (i.e. less framing bits). To determine the
* total octets of received frames, including framing characters,
* multiply PORTn_RX_TTL_FRMS by 8 and add it to this stat (unless
* otherwise configured, this stat only counts frames that have 8
* bytes of preamble for each frame). This stat can be configured
* (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count everything,

* FCS, or length errors.
* @rx_offload_octets: Count of total octets, not including framing
* characters, of offloaded received frames that are passed
* to the host.
* @rx_vld_mcast_frms: Count of successfully received MAC frames containing a
* nonbroadcast group address. Does not include frames received
* with frame-too-long, FCS, or length errors.
* @rx_vld_bcast_frms: Count of successfully received MAC frames containing
* the broadcast group address. Does not include frames received
* with frame-too-long, FCS, or length errors.
* @rx_accepted_ucast_frms: Count of successfully received frames containing
* a unicast address. Only includes frames that are passed to
* the system.
* @rx_accepted_nucast_frms: Count of successfully received frames containing
* a non-unicast (broadcast or multicast) address. Only includes
* frames that are passed to the system. Could include, for instance,
* non-unicast frames that contain FCS errors if the MAC_ERROR_CFG
* register is set to pass FCS-errored frames to the host.
* @rx_tagged_frms: Count of received frames containing a VLAN tag.
* @rx_long_frms: Count of received frames that are longer than RX_MAX_PYLD_LEN
* + 18 bytes (+ 22 bytes if VLAN-tagged).
* @rx_usized_frms: Count of received frames of length (including FCS, but not
* framing bits) less than 64 octets, that are otherwise well-formed.
* In other words, counts runts.
* @rx_osized_frms: Count of received frames of length (including FCS, but not
* framing bits) more than 1518 octets, that are otherwise
* well-formed. Note: If register XMAC_STATS_GLOBAL_CFG.VLAN_HANDLING
* is set to 1, then "more than 1518 octets" becomes "more than 1518
* (1522 if VLAN-tagged) octets".
* @rx_frag_frms: Count of received frames of length (including FCS, but not
* framing bits) less than 64 octets that had bad FCS. In other

* is full and the receive path is backing up.
* @rx_red_discard: Count of received frames that are discarded because of RED
* (Random Early Discard).
* @rx_xgmii_ctrl_err_cnt: Maintains a count of unexpected or misplaced control

* Only increments the count by one for each XGMII column.
* @rx_xgmii_data_err_cnt: Maintains a count of unexpected control characters
* during normal data transmission. If the Reconciliation Sublayer
* (RS) receives a control character, other than a terminate control

* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
* to /E/ (i.e. the error character), thus the statistic tracks the
* number of Error characters received at any time.
* @rx_xgmii_err_sym: Count of the number of symbol errors in the received
* XGMII data (i.e. PHY indicates "Receive Error" on the XGMII).
* Only includes symbol errors that are observed between the XGMII
* Start Frame Delimiter and End Frame Delimiter, inclusive. And
* only increments the count by one for each frame.
* @rx_xgmii_column1_match: Maintains a count of the number of XGMII columns
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_COLUMN1_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns received at any
* time.
* @rx_xgmii_char2_match: Maintains a count of the number of XGMII characters
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
* to /E/ (i.e. the error character), thus the statistic tracks the
* number of Error characters received at any time.
* @rx_local_fault: Maintains a count of the number of times that link
* transitioned from "up" to "down" due to a local fault.
* @rx_xgmii_column2_match: Maintains a count of the number of XGMII columns
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_COLUMN2_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns received at any
* time. If XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is set
* to 1, then this stat increments when COLUMN2 is found within 'n'
* clocks after COLUMN1. Here, 'n' is defined by
* XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set to
* 0, then it means to search anywhere for COLUMN2).
* @rx_jettison: Count of received frames that are jettisoned because internal
* buffers are full.
* @rx_remote_fault: Maintains a count of the number of times that link
* transitioned from "up" to "down" due to a remote fault.

vxge: Fix a receive stall due to driver being out of synch with chip. - Fix a receive stall due to driver being out of synch with chip. In a corner case scenario the adapter's ring controller may return a RxD with transfer code of 0xC, while the host ownership bit is still set to the adapter. The driver needs to assume that this case where (host_ownership == 1 or adapter) and (transfer_code == 0xC) is valid, that is, this RxD has been returned by the receive ring controller but no frame data is associated with the rxd. - Restore the transfer code field of each newly replenished RxD to 0x0. - Code cleanup.

vxge: Fix starvation of receive ring controller when blasted by short packets. - Fix starvation of receive ring controller when blasted by short packets. This was because the driver was posting 64 rxds initially while the ring controller was expecting to read 256 replenished rxds. While the driver was coming up, the internal rxd memory filled up the 64 buffers provided and the ring controller was left waiting for the remaining 192 rxds to complete the write back of completed rxds to the host and generation of an interrupt.

vxge: fix pktgen hangs (don't abuse skb->cb[]) This patch fixes a case in the transmit completion code which was resulting in pktgen hanging at the end of a run. The cause is due to the fact that the ->cb[] area of an skb cannot be used in a network driver's transmit path, as that area belongs to the network protocol. Pktgen hangs, as it sends out the same packet multiple times, and vxge's use of this area of the skb for a temporary list can only add the packet to the temporary list once (while it may be on the queue many times). The fix is to remove this abuse of skb->cb[]. Instead, skb pointers are placed into a temporary stack array, and then free outside of the tx lock. This retains the smp optimization of doing dev_kfree_skb() outside of the tx lock.
