Merge branch 'hinic-mailbox-channel-enhancement'
Luo bin says: ==================== hinic: mailbox channel enhancement add support to generate mailbox random id for VF to ensure that the mailbox message from VF is valid and PF should check whether the cmd from VF is supported before passing it to hw. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
