Upon receiving FLR IRQ for a RVU PF, teardown or cleanup
resources held by that PF_FUNC. This patch cleans up,
NIX LF
- Stop ingress/egress traffic
- Disable NPC MCAM entries being used.
- Free Tx scheduler queues
- Disable RQ/SQ/CQ HW contexts
NPA LF
- Disable Pool/Aura HW contexts
In future teardown of SSO/SSOW/TIM/CPT will be added.
Also added a mailbox message for a RVU PF to request
AF, to perform FLR for a RVU VF under it.

RVU admin function (AF) has all the priviliges to cleanup
HW state when VFIO triggers a PCIe function level reset (FLR)
due to either reset or a VM crash. FLR for RVU PF1-PFn will
trigger an IRQ to AF.
This patch enables all RVU PF's FLR interrupts and registers a
handler. Upon receiving an interrupt, a workqueue is scheduled
to cleanup all hardware blocks being used by the PF which
received the FLR.

This works by shadowing existing UCAST MCAM entry
with a new one additionally matching either NPC_LT_LB_CTAG
or NPC_LT_LB_STAG. For this to fully work one needs to
send properly configured NIX_VTAG_CFG message afterwards i.e with
strip and capture enabled and type set to 0.
On receiving tagged packet NIX will remove outer VLAN and capture
TCI in NIX_RX_PARSE_S.
Also simplified RX Vtag configuration flow
With this setting STRIP/CAPTURE VTAG actions separately would be
possible. Following combinations are possible: STRIP,
STRIP and CAPTURE, CAPTURE or nothing (0 disables respective actions).

For a PF/VF with a NIXLF attached has default/reserved MCAM entries

forwarded to NIXLF only after it's contexts are initialized. This
patch keeps these default entries disabled and adds mbox messages

Likewise while PF/VF is being teared down, it can send the disable

The DPNI object on which we build a network interface has a
certain number of {Rx, Tx, Tx confirmation} frame queues as
resources. The default hardware setup offers one queue of each
type, as well as one DPCON channel, for each core available
in the system.
There are however cases where the number of queues is greater
than the number of cores or channels. Until now, we configured
and used all the frame queues associated with a DPNI, even if it
meant assigning multiple queues of one type to the same channel.
Update the driver to only use a number of queues equal to the
number of channels, ensuring each channel will contain exactly
one Rx and one Tx confirmation queue.
>From the user viewpoint, this change is completely transparent.
Performance wise there is no impact in most scenarios. In case
the number of queues is larger than and not a multiple of the
number of channels, Rx hash distribution offers now better load
balancing between cores, which can have a positive impact on
overall system performance.

Using 2.5G speed relies on the SerDes lanes being configured
accordingly. The lanes have to be reconfigured to switch between
1G and 2.5G, and for now only the bootloader does this configuration.
In the case we add a Comphy driver to handle switching the lanes
dynamically, it's better for now to stick with supporting only 1G and
add advertisement for 2.5G once we really are capable of handling both
speeds without problem.
Since the interface mode is initialy taken from the DT, we want to make
sure that adding comphy support won't break boards that don't update

When re-registering a user mr, the mpt information for the
existing mr when running SRIOV is obtained via the QUERY_MPT
fw command. The returned information includes the mpt's lkey.
This retrieved mpt information is used to move the mpt back
to hardware ownership in the rereg flow (via the SW2HW_MPT
fw command when running SRIOV).
The fw API spec states that for SW2HW_MPT, the lkey field
must be zero. Any ConnectX-3 PF driver which checks for strict spec
adherence will return failure for SW2HW_MPT if the lkey field is not
zero (although the fw in practice ignores this field for SW2HW_MPT).
Thus, in order to conform to the fw API spec, set the lkey field to zero
before invoking SW2HW_MPT when running SRIOV.
