Subject[PATCH net-next 2/3] net: hns3: refactor the mailbox message between PF and VF
Date
From: Yufeng Mo <moyufeng@huawei.com>

For making the code more readable, this adds several new
structure to replace the msg field in structure
hclge_mbx_vf_to_pf_cmd and hclge_mbx_pf_to_vf_cmd.
Also uses macro to instead of some magic number.
