Subject: [PATCH 1/1] ixgbevf: replace enum with MACROs

From: Zhu Yanjun <zyjzyj2000@...il.com>

With the original enum, when a several bits state is set, it is
possible that the wrong test occurs.

For example,

a state is 0x3, its bits are 11. When testing a state 0x2 whose
bits are 10, it is difficult to confirm that state 0x2 is set or
not.

As such, the MACROs are defined to avoid the above error.
