Commit Message

shenjian (K) April 19, 2022, 2:22 a.m. UTC
Replace the direct using for features members of netdev
with netdev_xxx_features helpers, for the nic drivers are
not supposed to modify netdev_features directly.

I'mo not sure for this patch is necessary, just keep the
same rule with others.
