[PATCH net-next] bonding: set xfrm feature flags more sanely

From: Jarod Wilson
Date: Sat Dec 05 2020 - 13:20:06 EST


We can remove one of the ifdef blocks here, and instead of setting both
the xfrm hw_features and features flags, then unsetting the the features
flags if not in AB, wait to set the features flags if we're actually in AB
mode.
