Subject: ixgbevf: Rename MSGTYPE to SUCCESS and FAILURE
Patch-mainline: v5.17-rc1
Git-commit: 0edbecd5705728e803a56d646194f4ccdef5845f
References: bsc#1196426 CVE-2021-33061
There is name similarity within IXGBE_VT_MSGTYPE_ACK and
PFMAILBOX.ACK / VFMAILBOX.ACK. MSGTYPE macros are renamed to SUCCESS and
FAILURE because they are not specified in datasheet and now will be
easily distinguishable.
