[PATCH net-next 12/12] net: hns3: some variable modification

From: Huazhong Tan
Date: Thu Jun 13 2019 - 11:53:57 EST

From: Weihang Li <liweihang@xxxxxxxxxxxxx>

This patch does following things:
1. add the keyword const before some variables which won't be modified
in functions.
2. changes some variables from signed to unsigned to avoid bitwise
operation on signed variables.
3. adds or removes initialization of some variables.
4. defines a new structure to help parsing mailbox messages instead of
using an array which is harder to get the meaning of each element.
