Subject: [PATCH net-next v2 1/3] bnxt_en: Add support to call FW to update a VNIC
From: Michael Chan <michael.chan@...adcom.com>
Add the HWRM_VNIC_UPDATE message structures and the function to
send the message to firmware. This message can be used when
disabling and enabling a receive ring within a VNIC. The mru
which is the maximum receive size of packets received by the
VNIC can be updated.
