The i40e_add_pd_table_entry() routine is being modified to handle both
cases where a backing page is passed and where backing page is allocated
in i40e_add_pd_table_entry().
For PBLE resource management, it is more efficient for it to manage its
backing pages. For VF, PBLE backing page addresses will be send to PF
driver for PBLE resource.
The i40e_remove_pd_bp() is also modified to not free pre-allocated pages and
free only ones which were allocated in i40e_add_pd_table_entry().

During close, all of the MAC filters are cleared, so the driver would be
unable to receive unicast packets after being closed and reopened.
Add the adapter's "hardware" MAC address filter in open, not init. This
ensures that the correct filter is present each time.

Due to an inverted conditional, the driver was marking all of its MAC
filters for deletion every time set_rx_mode was called. Depending upon
the timing of the calls to set_rx_mode and the processing of the admin
queue, the driver would (accidentally) end up with a varying number of
functional filters.
Correct this logic so that MAC filters are added and removed correctly.
Add a check for the driver's "hardware" MAC address so that this filter
doesn't get removed incorrectly.

The VF disable code was just whanging on the reset bit without properly

from which it could not recover. Fix this by notifying the VF and then
by calling the normal VF reset routine.

MAC filters for VFs were being programmed with 0 for the VLAN value when
there was no VLAN assigned. This is incorrect and actually assigns the
VF to VLAN 0. Instead, we must use -1 to indicate that no VLAN is in
use. This change programs the filters correctly and gets rid of a bogus
error message when setting a port VLAN on an active VF.

The driver currently only maps TX and RX queues to a single MSI-X vector
per queue pair if there are exactly enough vectors for this.
Unfortunately, if we have too many vectors it will fail and allocate
queues to vectors in a suboptimal manner. Change the condition check to
allow for excess vectors. In this case, the extras just won't be used.

Commit 514ac99c64b "can: fix multiple delivery of a single CAN frame for
overlapping CAN filters" requires the skb->tstamp to be set to check for
identical CAN skbs.
Without timestamping to be required by user space applications this timestamp
was not generated which lead to commit 36c01245eb8 "can: fix loss of CAN frames
in raw_rcv" - which forces the timestamp to be set in all CAN related skbuffs
by introducing several __net_timestamp() calls.
This forces e.g. out of tree drivers which are not using alloc_can{,fd}_skb()
to add __net_timestamp() after skbuff creation to prevent the frame loss fixed
in mainline Linux.
This patch removes the timestamp dependency and uses an atomic counter to
create an unique identifier together with the skbuff pointer.
Btw: the new skbcnt element introduced in struct can_skb_priv has to be
initialized with zero in out-of-tree drivers which are not using
alloc_can{,fd}_skb() too.

The previous change 3973c526ae9c (net: can: c_can: Disable pins when CAN
interface is down) causes a slight glitch on the pinctrl settings when used.
Since commit ab78029 (drivers/pinctrl: grab default handles from device core),
the device core will automatically set the default pins. This causes the pins
to be momentarily set to the default and then to the sleep state in
register_c_can_dev(). By adding an optional "enable" state, boards can set the
default pin state to be disabled and avoid the glitch when the switch from
default to sleep first occurs. If the "enable" state is not available
c_can_pinctrl_select_state() falls back to using the "default" pinctrl state.

NCM specs are not actually mandating a specific position in the frame for
the NDP (Network Datagram Pointer). However, some Huawei devices will
ignore our aggregates if it is not placed after the datagrams it points
to. Add support for doing just this, in a per-device configurable way.
While at it, update NCM subdrivers, disabling this functionality in all of
them, except in huawei_cdc_ncm where it is enabled instead.
We aren't making any distinction between different Huawei NCM devices,
based on what the vendor driver does. Standard NCM devices are left
unaffected: if they are compliant, they should be always usable, still
stay on the safe side.
This change has been tested and working with a Huawei E3131 device (which
works regardless of NDP position), a Huawei E3531 (also working both
ways) and an E3372 (which mandates NDP to be after indexed datagrams).
V1->V2:
- corrected wrong NDP acronym definition
- fixed possible NULL pointer dereference
- patch cleanup

The limit for BQL is updated each time we call

Without this patch the BQL limit was updated for every TX event we

The issue was that this only updated the limit to handle the data
we complete in two events as the first event wouldn't show that
enough traffic had been processed between them.
This was OK when interrupt moderation was off but not when it was
on as more data had to be completed in a single interrupt.
The patch changes this so that we do report the completion to BQL
only when all the TX events in the interrupt have been processed.
