ce74370c2c net: hns3: optimize the barrier using when cleaning TX BD
Currently, a barrier is used when cleaning each TX BD, which may
cause performance degradation.

This patch optimizes it to use one barrier when cleaning TX BD
each round.

aa9d22dd45 net: hns3: fix error handling for desc filling
When desc filling fails in hns3_nic_net_xmit, it will call
hns3_clear_desc to unmap the dma mapping. But currently the
ring->next_to_use points to the desc where the desc filling
or dma mapping return error, which means the desc that
ring->next_to_use points to has not done the dma mapping,
the desc that need unmapping is before the ring->next_to_use.

This patch fixes it by calling ring_ptr_move_bw(next_to_use)
before doing unmapping operation, and set desc_cb->dma to
zero to avoid freeing it again when unloading.

Also, when filling skb head or frag fails, both need to unmap
all the way back to next_to_use_head, so remove one desc filling
error handling.

757cd1e4a4 net: hns3: combine len and checksum handling for inner and outer header.
When filling len and checksum info to description, there is some
similar checking or calculation.

So this patch adds hns3_set_l2l3l4 to fill the inner(/normal)
header's len and checksum info. If it is a encapsulation skb, it
calls hns3_set_outer_l2l3l4 to handle the outer header's len and
checksum info, in order to avoid some similar checking or
calculation.

39c38824c2 net: hns3: fix for tunnel type handling in hns3_rx_checksum
According to hardware user manual, the tunnel packet type is
available in the rx.ol_info field of struct hns3_desc. Currently
the tunnel packet type is decided by the rx.l234_info, which may
cause RX checksum handling error.

This patch fixes it by using the correct field in struct hns3_desc
to decide the tunnel packet type.

9bbb1c053b net: dsa: lantiq: Add VLAN aware bridge offloading
The VLAN aware bridge offloading is similar to the VLAN unaware
offloading, this makes it possible to offload the VLAN bridge
functionalities.

The hardware supports up to 64 VLAN bridge entries, we already use one
entry for each LAN port to prevent forwarding of packets between the
ports when the ports are not in a bridge, so in the end we have 57
possible VLANs.

The VLAN filtering is currently only active when the ports are in a
bridge, VLAN filtering for ports not in a bridge is not implemented.

It is currently not possible to change between VLAN filtering and not
filtering while the port is already in a bridge, this would make the
driver more complicated.

The VLANs are only defined on bridge entries, so we will not add
anything into the hardware when the port joins a bridge if it is doing
VLAN filtering, but only when an allowed VLAN is added.

8206e0ce96 net: dsa: lantiq: Add VLAN unaware bridge offloading
This allows to offload bridges with DSA to the switch hardware and do
the packet forwarding in hardware.

This implements generic functions to access the switch hardware tables,
which are used to control many features of the switch.

This patch activates the MAC learning by removing the MAC address table
lock, to prevent uncontrolled forwarding of packets between all the LAN
ports, they are added into individual bridge tables entries with
individual flow ids and the switch will do the MAC learning for each
port separately before they are added to a real bridge.

Each bridge consist of an entry in the active VLAN table and the VLAN
mapping table, table entries with the same index are matching. In the
VLAN unaware mode we configure everything with VLAN ID 0, but we use
different flow IDs, the switch should handle all VLANs as normal payload
and ignore them. When the hardware looks for the port of the destination
MAC address it only takes the entries which have the same flow ID of the
ingress packet.

The bridges are configured with 64 possible entries with these
information:
Table Index, 0...63
VLAN ID, 0...4095: VLAN ID 0 is untagged
flow ID, 0..63: Same flow IDs share entries in MAC learning table
port map, one bit for each port number
tagged port map, one bit for each port number

640f763f98 net: dsa: sja1105: Add support for Spanning Tree Protocol
While not explicitly documented as supported in UM10944, compliance with
the STP states can be obtained by manipulating 3 settings at the
(per-port) MAC config level: dynamic learning, inhibiting reception of
regular traffic, and inhibiting transmission of regular traffic.

In all these modes, transmission and reception of special BPDU frames
from the stack is still enabled (not inhibited by the MAC-level
settings).

On ingress, BPDUs are classified by the MAC filter as link-local
(01-80-C2-00-00-00) and forwarded to the CPU port.  This mechanism works
under all conditions (even without the custom 802.1Q tagging) because
the switch hardware inserts the source port and switch ID into bytes 4
and 5 of the MAC-filtered frames. Then the DSA .rcv handler needs to put
back zeroes into the MAC address after decoding the source port
information.

On egress, BPDUs are transmitted using management routes from the xmit
worker thread. Again this does not require switch tagging, as the switch
port is programmed through SPI to hold a temporary (single-fire) route
for a frame with the programmed destination MAC (01-80-C2-00-00-00).

STP is activated using the following commands and was tested by
connecting two front-panel ports together and noticing that switching
loops were prevented (one port remains in the blocking state):

$ ip link add name br0 type bridge stp_state 1 && ip link set br0 up
$ for eth in $(ls /sys/devices/platform/soc/2100000.spi/spi_master/spi0/spi0.1/net/);
  do ip link set ${eth} master br0 && ip link set ${eth} up; done

227d07a07e net: dsa: sja1105: Add support for traffic through standalone ports
In order to support this, we are creating a make-shift switch tag out of
a VLAN trunk configured on the CPU port. Termination of normal traffic
on switch ports only works when not under a vlan_filtering bridge.
Termination of management (PTP, BPDU) traffic works under all
circumstances because it uses a different tagging mechanism
(incl_srcpt). We are making use of the generic CONFIG_NET_DSA_TAG_8021Q
code and leveraging it from our own CONFIG_NET_DSA_TAG_SJA1105.

There are two types of traffic: regular and link-local.

The link-local traffic received on the CPU port is trapped from the
switch's regular forwarding decisions because it matched one of the two
DMAC filters for management traffic.

On transmission, the switch requires special massaging for these
link-local frames. Due to a weird implementation of the switching IP, by
default it drops link-local frames that originate on the CPU port.
It needs to be told where to forward them to, through an SPI command
("management route") that is valid for only a single frame.
So when we're sending link-local traffic, we are using the
dsa_defer_xmit mechanism.

49cbef1388 nfp: flower: add qos offload install and remove functionality.
Add install and remove offload functionality for qos offloads. We
first check that a police filter can be implemented by the VF rate
limiting feature in hw, then we install the filter via the qos
infrastructure. Finally we implement the mechanism for removing
these types of filters.

Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2019-05-04

This series contains updates to the ice driver only.

Jesse updated the driver to make more functions consistent in their use
of a local variable for vsi->back.  Updates the driver to use bit fields
when possible to avoid wasting lots of storage space to store single bit
values.  Optimized the driver to be more memory efficient by moving
structure members around that are not in are hot path.

Michal updates the driver to disable the VF if malicious device driver
(MDD) event is detected by the hardware.  Adds checks to validate the
messages coming from the VF driver.  Tightens up the sniffing of the
driver so that transmit traffic so that VF's cannot see what is on other
VSIs.

Tony fixed the driver so that receive stripping state won't change every
time transmit insertion is changed.  Cleanup the __always_unused
attribute, now that the variable is being used.  Fixed the function
which evaluates setting of features to ensure that can evaluate and set
multiple features in a single function call.

Akeem fixes the driver so that we do not attempt to remove a VLAN filter
that does not exist.  Adds support for adding a ethertype based filter
rule on VSI and describe it in a very long run-on sentence. :-)

Bruce cleans up static analysis warnings by removing a local variable
initialization that is not needed.

Brett makes the allocate/deallocate more consistent in all the driver
flows for VSI q_vectors.  In addition, makes setting/getting coalesce
settings more consistent throughout the driver.

Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2019-05-04

This series contains updates to i40e only.

Grzegorz fixes a bug with promiscuous mode not being kept when the VF
switched to a new VLAN.  Fixed a typo in the link mode code, by using
the correct define.  Fixed truncation issue, which changed an function
argument to a smaller value that should have been a larger value.

Aleksandr adds support for new x710 devices and the speeds they support.

Sergey adds a check for the number of vectors against the number of MSIx
vectors to ensure one does not exceed the other.

Martyna adds additional input validation on VF messages handled by the
PF.  Fixed potential memory leaks in the driver where the error paths
were not freeing allocated memory.

Maciej reverts the double ShadowRAM checksum calculation change because
issues were found in the NVM downgrade situation.

Gustavo Silva changes the i40e driver to use struct_size() in kzalloc()
calls, to avoid type mistakes.

d1f5050b45 r8169: speed up rtl_loop_wait
When testing I figured out that most operations signal finish even
before we trigger the first delay. Seems like PCI(e) access and
memory barriers typically add enough latency. Therefore move the
first delay after the first check.
