With autoneg enabled, PHY loopback test fails. To disable autoneg,
driver needs to send a valid forced speed to FW. FW is not sending
async event for invalid speeds. To fix this, query forced speeds
and send the correct speed when disabling autoneg mode.

Port statistics which include RDMA counters are useful even when the
netdevice is down. Do not free the port statistics DMA buffers
when the netdevice is down. This is keep the snapshot of the port
statistics and counters will just continue counting when the
netdevice goes back up.
Split the bnxt_free_stats() function into 2 functions. The port
statistics buffers will only be freed when the netdevice is
removed.

With the current driver, the statistics reported by .ndo_get_stats64()
are reset when the device goes down. Store a snapshot of the
rtnl_link_stats64 before shutdown. This snapshot is added to the
current counters in .ndo_get_stats64() so that the counters will not
get reset when the device is down.

Display the CoS counters as additional priority counters by looking up
the priority to CoS queue mapping. If the TX extended port statistics
block size returned by firmware is big enough to cover the CoS counters,
then we will display the new priority counters. We call firmware to get
the up-to-date pri2cos mapping to convert the CoS counters to
priority counters.

There are some minor differences when assigning VF resources on the

When bringing up a device, the code checks to see if the number of
MSIX has changed. pci_disable_msix() should be called first before
changing the number of reserved NQs/CMPL rings. This ensures that
the MSIX vectors associated with the NQs/CMPL rings are still
properly mapped when pci_disable_msix() masks the vectors.
This patch will prevent errors when RDMA support is added for the new
57500 chips. When the RDMA driver shuts down, the number of NQs is
decreased and we must use the new sequence to prevent MSIX errors.

bnxt_en requires same number of stat_ctxs as CP rings but RDMA
requires only 1 stat_ctx. Also add a new parameter resv_stat_ctxs
to better keep track of stat_ctxs reserved including resources used
by RDMA. Add a stat_ctxs parameter to all the relevant resource
reservation functions so we can reserve the correct number of
stat_ctxs.
Prior to this patch, we were not reserving the extra stat_ctx for
RDMA and RDMA would not work on the new 57500 chips.

Calling bnxt_set_max_func_stat_ctxs() to modify max stat_ctxs requested
or freed by the RDMA driver is wrong. After introducing reservation of
resources recently, the driver has to keep track of all stat_ctxs
including the ones used by the RDMA driver. This will provide a better
foundation for accurate accounting of the stat_ctxs.

The PF has a pool of NQs and MSIX vectors assigned to it based on
NVRAM configurations. The number of usable MSIX vectors on the PF
is the minimum of the NQs and MSIX vectors. Any excess NQs without
associated MSIX may be used for the VFs, so we need to store this
max_nqs value. max_nqs minus the NQs used by the PF will be the
available NQs for the VFs.

Take care of setup/teardown for the port link, dcb, lag as well as
dealing with port mtu and carrier for e-switch uplink representors.
This is achieved by adding a dedicated profile instance for uplink

which are invoked by the general mlx5e code for netdev attach/detach.

Now, when we have a dedicated uplink representor, the netdev instance
set over the esw manager vport (PF) is of no-use. As such, remove it
once we're on switchdev mode and get it back to life when off switchdev.
This is done by reloading the Ethernet interface as well (we already
do that for the IB interface) from the eswitch code while going in/out
of switchdev mode.
The Eth add/remove entries are modified to act differently when called in
switchdev mode. In this case we only deal with registration of the eth
vport representors. The rep netdevices are created from the eswitch call
to load the registered eth representors.

Currently, when running in sriov switchdev mode, we are using the PF
netdevice as the uplink representor, this is problematic from few aspects:
- will break when the PF isn't eswitch manager (e.g smart NIC env)
- misalignment with other NIC switchdev drivers
- makes us have and maintain special code, hurts the driver quality/robustness
- which in turn opens the door for future bugs
As of each and all of the above, we move to have a dedicated netdev representor
for the uplink vport in a similar manner done for for the VF vports.
This includes the following:
1. have an uplink rep netdev as we have for VF reps
2. all reps use same load/unload functions
3. HW stats for uplink based on physical port counters and not vport counters
4. link state for the uplink managed through PAOS and not vport state
5. the uplink rep has sysfs link to the PF PCI function && uses the PF MAC address

Bloom filter is updated on transitions from a single rule pattern,
also called master RP, to eRP table and vice versa. Since rules are
being written to or deleted from the Bloom filter on such transitions,
it is not required to keep the same eRP bank ID for the master RP.
Change master RP index assignment so it will be assigned with zero.
This is consistent with the assignment of the first available spot
that is used for allocating eRP's indices.

Bloom filter update is required only for rules which reside on an
eRP. When the region has only a single rule pattern then eRP table
is not used, however insertion of another pattern would trigger a
move to an active eRP table so it is imperative to update the Bloom
filter with all previously configured rules.
Add a method that updates Bloom filter entries for all rules
currently configured in the region, on the event of a transition
from master mask to eRP, or vice versa. For that purpose, maintain
a list of all A-TCAM rules within mlxsw_sp_acl_atcam_region.

Spectrum-2 HW uses Bloom filter in order to skip lookups on specific
eRPs. It uses crc-16-Msbit-first calculation over a specific layout
of a rule's key fields combined with eRP ID as well as region ID.
Per potential lookup, iff the Bloom filter entry of the calculated
index is empty, then the lookup can be skipped. Hence, the mlxsw
driver should update the Bloom filter entry per each rule insertion
or deletion when rules are part of an eRP.
Add functions for adding and deleting entries in the Bloom filter.
In order to do so also add crc-16 computation based on the specific
Spectrum-2 polynomial and a function for encoding the crc-16 input
in the manner dictated by HW implementation.

====================
mlx5e-updates-2018-12-14 (VF Lag)
From Aviv Heller,
Subsequent patches introduce VF LAG, which provdies load-balancing and
high-availability capabilities for VFs associated with different
physical ports of the same Connect-X card.
This series consists of the following:
- mlx5 devcom, driver infrastructure that facilitates operations that involve
both core devices (physical functions) of the same card, to synchronize and
communicate between two driver instances of the same card.
- Infrastructure for TC rule duplication.
- Changes to LAG logic to enable its use when SR-IOV is enabled
- PFs in switchdev mode is the only mode currently supported.

Currently the driver issues 2 mmio reads to figure out the number of
transmitted packets and clean them. We can get rid of the expensive
reads since BIT 31 of the Tx descriptor can be used for that.
We can also remove the budget counting of Tx completions since all of
the descriptors are not deliberately processed.
Performance numbers using pktgen are:

Running pktgen with packets sizes > 512b ends up in the interface Txq
getting stuck.
"netsec 522d0000.ethernet eth0: netsec_netdev_start_xmit: TxQFull!"
appears on dmesg but the interface never recovers. It requires an
ifconfig down/up to make the interface usable again.
The reason that triggers this, is a race condition between
.ndo_start_xmit and the napi completion. The available budget is
calculated first and indicates the queue is full. Due to a costly
netif_err() the queue is not stopped in time while the napi completion
runs, clears the irq and frees up descriptors, thus the queue never wakes
up again.
Fix this by moving the print after stopping the queue, make the print
ratelimited, add barriers and check for cleaned descriptors..
