VMware expects that certain kind of configurations made on the VFs are
authorized by the ESXi before these are applied e.g. assigning a MAC
address to the VF, setting MTU etc. Firmware supports a feature called
MCDI proxy which will be used to implement this authorization check.
The proxy auth module is governed by EFSYS_OPT_MCDI_PROXY_AUTH switch.
This patch adds the framework for proxy auth module along with the APIs
required for SR-IOV initialization.

ef10_nic_init() allocates a vAdaptor for the physical port in current
flow. In case of SR-IOV, this vAdaptor must be created for the PF as the
vSwitch is allocated on the physical port. So, the call to
efx_mcdi_vadaptor_alloc() should be avoided in ef10_nic_init() in SR-IOV
flow. To achieve this, for SR-IOV use case, the vSwitch is created
before NIC initialization and its handle is used to prevent vAdaptor
allocation in ef10_nic_init(). This approach has been taken to minimize
the changes in NIC initialization flow.
This is also the case with Linux driver where vSwitch creation happens
before NIC initialization.
Also, when DMA queues need to be allocated for Tx/Rx functionality
(MC_CMD_INIT_RXQ / MC_CMD_INIT_TXQ), the correct vPort is selected
based on efx_vswitch_t property of efx_nic_t structure - vport
corresponding to PF in case of SR-IOV use case and EVB_PORT_ID_ASSIGNED
for physical port.

When WQEs are posted to the HW to send packets, the PMD may get a
completion report with error from the HW, aka error CQE which is
associated to a bad WQE.
The error reason may be bad address, wrong lkey, bad sizes, etc.
that can wrongly be configured by the PMD or by the user.
Checking all the optional mistakes to prevent error CQEs doesn't make
sense due to performance impacts and huge complexity.
The error CQEs change the SQ state to error state what causes all the
next posted WQEs to be completed with CQE flush error forever.
Currently, the PMD doesn't handle Tx error CQEs and even may crashed
when one of them appears.
Extend the Tx data-path to detect these error CQEs, to report them by
the statistics error counters, to recover the SQ by moving the state
to ready again and adjusting the management variables appropriately.
Sometimes the error CQE root cause is very hard to debug and even may
be related to some corner cases which are not reproducible easily, hence
a dump file with debug information will be created for the first number
of error CQEs, this number can be configured by the PMD probe
parameters.

When WQEs are posted to the HW to receive packets, the PMD may receive
a completion report with error from the HW, aka error CQE which is
associated to a bad WQE.
The error reason may be bad address, wrong lkey, small buffer size,
etc. that can wrongly be configured by the PMD or by the user.
Checking all the optional mistakes to prevent error CQEs doesn't make
sense due to performance impacts, moreover, some error CQEs can be
triggered because of the packets coming from the wire when the DPDK
application has no any control.
Most of the error CQE types change the RQ state to error state what
causes all the next received packets to be dropped by the HW and to be
completed with CQE flush error forever.
The current solution detects these error CQEs and even reports the
errors to the user by the statistics error counters but without
recovery, so if the RQ inserted to the error state it never moves to
ready state again and all the next packets ever will be dropped.
Extend the error CQEs handling for recovery by moving the state to
ready again, and rearranging all the RQ WQEs and the management
variables appropriately.
Sometimes the error CQE root cause is very hard to debug and even may

There is a full correlation between the CQE indexes to the WQE indexes
in the vectorized Rx queues management.
When the RQ is inserted to the reset state, the correlation may break
because the HW starts the RQ polling from index 0 while the CQ polling
continues regularly.
As an arrangement to CQE errors handling, when the RQ can be reset,
the correlation dependence should be removed from all the Rx queues
index managements.
