If register_netdev() fails, the driver will attempt to cleanup the
q_vectors and inadvertently trigger a kernel BUG due to a NULL pointer
dereference.
This occurs because cleaning up q_vectors attempts to call
netif_napi_del on napi_structs which were never initialized.
Resolve this by releasing the netdev in ice_cfg_netdev and setting
vsi->netdev to NULL. This ensures that after ice_cfg_netdev fails the
state is rewound to match as if ice_cfg_netdev was never called.

100GbE Intel Wired LAN Driver Updates 2020-05-27
This series contains updates to the ice driver only.
Jesse fixes a number of issues, starting with fixing the remaining
signed versus unsigned comparison issues. Cleaned up an unused code
define. Fixed the implementation of the manage MAC write command, to
simplify it by using a simple array to represent the MAC address when
writing it.
Paul fixes the setting of the VF default LAN address, by removing a
check that assumed that the address had been deleted and zeroed.
Surabhi prevents a memory leak on filter management initialization
failures and during queue initialization and buffer allocation failures.
Brett adds additional receive error counters that are reported by
ethtool. Fixed the enabling and disabling of VLAN stripping when the
PVID has been set.
Evan fixes a race condition between the firmware and software, which can
occur between the admin queue setup and the first command sent.
Marta fixes the driver when XDP transmit rings are destroyed, also make
sure the XDP transmit queues are also destroyed. Update the statistics
when XDP transmit programs are loaded and packets are sent. Changed the
number of XDP transmit queues to match the number of receive queues,
instead of matching the number of transmit queues.
Bruce avoids undefined behavior by not writing the 8-bit element
init_q_state with the associated internal-to-hardware field which is
122-bits.
Anirudh (Ani) refactors the receive checksum checks.

Summary:
--------
Problem statement:
------------------
Currently in above topology, when netfailover device is configured using
VFs and eswitch VF representors, and when traffic fails over to stand-by
VF which is exposed using macvtap device to guest VM, eswitch fails to
switch the traffic to the stand-by VF representor. This occurs because
there is no knowledge at eswitch level of the stand-by representor
device.
Solution:
---------
Using standard bonding driver, a bond netdevice is created over VF
representor device which is used for offloading tc rules.
Two VF representors are bonded together, one for the passthrough VF
device and another one for the stand-by VF device.
With this solution, mlx5 driver listens to the failover events
occuring at the bond device level to failover traffic to either of
the active VF representor of the bond.
a. VM with netfailover device of VF pass-thru (PT) device and virtio-net
paravirtualized device with same MAC-address to handle failover
traffics at VM level.
b. Host bond is active-standby mode, with the lower devices being the VM
VF PT representor, and the representor of the 2nd VF to handle
failover traffics at Hypervisor/V-Switch OVS level.
- During the steady state (fast datapath): set the bond active
device to be the VM PT VF representor.
- During failover: apply bond failover to the second VF representor
device which connects to the VM non-accelerated path.
c. E-Switch ingress/egress ACL tables to support failover traffics at
E-Switch level
I. E-Switch egress ACL with forward-to-vport rule:
- By default, eswitch vport egress acl forward packets to its
counterpart NIC vport.
- During port failover, the egress acl forward-to-vport rule will
be added to e-switch vport of passive/in-active slave VF
representor
to forward packets to other e-switch vport ie. the active slave
representor's e-switch vport to handle egress "failover"
traffics.
- Using lower change netdev event to detect a representor is a
lower
dev (slave) of bond and becomes active, adding egress acl
forward-to-vport rule of all other slave netdevs to forward to
this
representor's vport.
- Using upper change netdev event to detect a representor unslaving
from bond device to delete its vport's egress acl forward-to-vport
rule.
II. E-Switch ingress ACL metadata reg_c for match
- Bonded representors' vorts sharing tc block have the same
root ingress acl table and a unique metadata for match.
- Traffics from both representors's vports will be tagged with same
unique metadata reg_c.
- Using upper change netdev event to detect a representor
enslaving/unslaving from bond device to setup shared root ingress
acl and unique metadata.

SJA1105, being AVB/TSN switches, provide hardware assist for the
Credit-Based Shaper as described in the IEEE 8021Q-2018 document.
First generation has 10 shapers, freely assignable to any of the 4
external ports and 8 traffic classes, and second generation has 16
shapers.
The Credit-Based Shaper tables are accessed through the dynamic
reconfiguration interface, so we have to restore them manually after a
switch reset. The tables are backed up by the static config only on
P/Q/R/S, and we don't want to add custom code only for that family,
since the procedure that is in place now works for both.

mt76 core uses ffs() to find the next free bit. This works well for 32 bit
architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so
allocation fails on 64 bit architectures.
Additionally, the wcid mask array was too small in cases where the array
was not a multiple of BITS_PER_LONG.
Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP
for the size, just in case we ever bump it to a value that's not a multiple
of 32.

If a UMEM is present on a queue when an interface/queue pair is being
enabled, the driver will try to prepare the Rx buffers in advance to
improve performance. However, if fill queue is shorter than HW Rx ring,
the driver will report failure after getting the last address from the
fill queue.
This still lets the driver process the packets correctly during the NAPI
poll, but leads to a constant NAPI rescheduling. Not allocating the
buffers in advance would result in a potential performance decrease.
Commit d57d76428ae9 ("xsk: Add API to check for available entries in FQ")
provides an API that lets drivers check the number of addresses that the
fill queue holds.
Notify the user if fill queue is not long enough to prepare all buffers
before packet processing starts, and allocate the buffers during the
NAPI poll. If the fill queue size is sufficient, prepare Rx buffers in
advance.

Change the locking flow to support RX and TX locks, splitting
the single lock to two will allow inserting rules in parallel
for RX and TX parts of the FDB.
Locking the dr_domain will be done by locking the RX domain
and the TX domain locks, this is mostly used for control operations
on the dr_domain. When inserting rules for RX or TX the single
nic_doamin RX or TX lock will be used. Splitting the lock is safe since
RX and TX domains are logically separated from each other, shared
objects such the send-ring and memory pool are protected by locks.

Bonded slave representors' vports must share a unique metadata
for match.
On enslaving event of slave representor to lag device, allocate
new unique "bond_metadata" for match if this is the first slave.
The subsequent enslaved representors will share the same unique
"bond_metadata".
On unslaving event of slave representor, reset the slave
representor's vport to use its own default metadata.
Replace ingress acl and rx rules of the slave representors' vports
using new vport->bond_metadata.

Introduce infrastructure to create unique metadata for match
for vport without depending on vport_num. Vport uses its
default metadata for match in standalone configuration but
will share a different unique "bond_metadata" for match with
other vports in bond configuration.

When a bond device is created over one or more non uplink representors,
and when a flow rule is offloaded to such bond device, offload a rule
to the active lower device.
Assuming that this is active-backup lag, the rules should be offloaded
to the active lower device which is the representor of the direct
path (not the failover).

Currently offloading a rule over a tc block shared by multiple
representors fails because an e-switch global hashtable to keep
the mapping from tc cookies to mlx5e flow instances is used, and
tc block sharing offloads the same rule/cookie multiple times,
each time for different representor sharing the tc block.
Changing the implementation and behavior by acknowledging and returning
success if the same rule/cookie is offloaded again to other slave
representor sharing the tc block by setting, checking and comparing
the netdev that added the rule first.

By default, e-switch vport's egress acl just forward packets to its
counterpart NIC vport using existing egress acl table.
During port failover in bonding scenario where two VFs representors
are bonded, the egress acl forward-to-vport rule will be added to
the existing egress acl table of e-switch vport of passive/inactive
slave representor to forward packets to other NIC vport ie. the active
slave representor's NIC vport to handle egress "failover" traffic.
Enable egress acl and have APIs to create and destroy egress acl
forward-to-vport rule and group.
