The virtchnl message is handled one by one by checking opcode to match
the response for the request.
The DCF AdminQ command with buffer needs two virtchnl commands, one is
to handle the AdminQ descriptor, the other is to the handle AdminQ
buffer. If both of them are sent to PF successfully, it needs to wait
two responses from PF, even if the AdminQ descriptor command gets the
failure response. Since PF will handle them one by one, and send back
the response for each.
If not wait for the buffer message response until timeout to drain out
the virtchnl command queue, it will cause the next AdminQ command with
buffer to get the stall buffer response from previous.

The initialization of selecting the handler for scalar Rx path FlexiMD

Also add the missed support to handle RXDID 16, which has RSS hash value

If there's VF reset, the kernel PF will remove rules
associated with the reset VF no matter the HW VSI ID
is changed or not. So DCF should redirector all rules
associated with the reset VF no matter the HW VSI ID

The DCF (Device Config Function) needs the hardware index of the VFs to
control the flow setting. And also if the VF resets, the index may be
changed, so it should handle this in VF reset event.

The DCF (Device Config Function) works at the user PF level, it can't
access the real PF hardware directly. So it will pass through the PF's
AdminQ command by the DCF's mailbox.
And the DCF is mainly used to control the flow setting of other VFs, so
it only needs to initialize some core functions related to the flow.

The DCF (Device Config Function) splits the AdminQ command into two
parts: one is the descriptor of AdminQ command, the other is the buffer
of AdminQ command (the descriptor has BUF flag set). When both of them
are received by the PF, the PF will handle them as one command.
And also, the filled descriptor and buffer of the response will be sent
back to DCF one by one through the virtchnl from PF.
