The main changes are:
1. HWRM_VNIC_UPDATE used to safely disable and enable an RX ring within
the VNIC.
2. New flag in HWRM_VNIC_QCAPS to indicate FW will do the proper flush
during HWRM_VNIC_UPDATE.
3. New flag in HWRM_FUNC_QCAPS to indicate that reservations for some
resources such as VNIC can be reduced.
4. New backing store memory types not used by the driver yet.

Pull rdma updates from Jason Gunthorpe:
"Many small changes across the subystem, some highlights:
- Usual driver cleanups in qedr, siw, erdma, hfi1, mlx4/5, irdma,
mthca, hns, and bnxt_re
- siw now works over tunnel and other netdevs with a MAC address by
removing assumptions about a MAC/GID from the connection manager
- "Doorbell Pacing" for bnxt_re - this is a best effort scheme to
allow userspace to slow down the doorbell rings if the HW gets full
- irdma egress VLAN priority, better QP/WQ sizing
- rxe bug fixes in queue draining and srq resizing
- Support more ethernet speed options in the core layer
- DMABUF support for bnxt_re
- Multi-stage MTT support for erdma to allow much bigger MR
registrations
- A irdma fix with a CVE that came in too late to go to -rc, missing
bounds checking for 0 length MRs"

Fix the following warning:

cc1: error: writing 12 bytes into a region of size 1 [-Werror=stringop-overflow ]

drivers/net/ethernet/broadcom/bnxt/bnxt_hsi.h:6045:17: note: destination object ‘unused_0’ of size 1

Fix it by modifying struct hwrm_queue_cos2bw_cfg_input to use an array
of sub struct similar to the previous patch. This will eliminate the
pointer arithmetc to calculate the destination pointer passed to
memcpy().

Modify the FW interface defintion of struct hwrm_queue_cos2bw_qcfg_output

the layout of the queue0 fields are different and these are not part of

Hardware is unable to realize all legal firmware interface state values
for hash_type. For example, if 4-tuple TCP_IPV4 hash is enabled,
4-tuple UDP_IPV4 hash must also be enabled. By providing the bits the
user intended to change instead of the possible illegal intermediate
states, the firmware is able to make better compromises when deciding
which bits to ignore.
With this new mechansim, we can now report the actual configured hash
back to the user. Add bnxt_hwrm_update_rss_hash_cfg() to report the
actual hash after user configuration.

The main changes include FEC, ECN statistics, HWRM_PORT_PHY_QCFG
response size reduction, and a new counter added to
ctx_hw_stats_ext struct to support the new 58818 chip.
The ctx_hw_stats_ext structure is now the superset supporting the new
58818 chips and the prior P5 chips. Add a new flag to identify the new
chip and use constants for the chip specific ring statistics sizes
instead of the size of the structure.
Because the HWRM_PORT_PHY_QCFG response structure size has shrunk back
to 96 bytes, the workaround added earlier to limit the size of this
message for forwarding to the VF can be removed.

Main changes are 200G support and fixing the definitions of discard and
error counters to match the hardware definitions.
Because the HWRM_PORT_PHY_QCFG message size has now exceeded the max.
encapsulated response message size of 96 bytes from the PF to the VF,
we now need to cap this message to 96 bytes for forwarding. The forwarded
response only needs to contain the basic link status and speed information
and can be capped without adding the new information.
