Looks better. Use it in v2.

msgbuf[0] |= index << IXGBE_VT_MSGINFO_SHIFT;
msgbuf[0] |= IXGBE_VF_SET_MACVLAN;
"index != 0" has effect on the msgbuf[0], so we should emphasize on "index".
I will change it to "index is not 0" in v2.

It's different from 15/39 where the write buffer is simple,
Here the write buffer msgbuf[0] is more complicated, if we don't
introduce msgbuf_chk, the code will looks bloated.
