[dpdk-dev] [PATCH v2 27/36] net/ice/base: add the hook to send AdminQ command

[Qi Zhang]

Add the hook to send the PF's AdminQ command in another path, like not
directly to the firmware.

If the AdminQ command is sent through the hook path, it needs to save
the AQ error codes from firmware as the last status for admin control
queue, so that the AdminQ command function can use it to do exception
handling like the buffer size is not enough accorindg to error ENOMEM.

And convert explicitly the hook path result to the ice_status type.
