ah: Don't return NET_XMIT_DROP on input.
commit 4b90a603a1b21d63cf743cc833680cb195a729f6 upstream. When the ahash driver returns -EBUSY, AH4/6 input functions return NET_XMIT_DROP, presumably copied from the output code path. But returning transmit codes on input doesn't make a lot of sense. Since NET_XMIT_DROP is a positive int, this gets interpreted as the next header type (i.e., success). As that can only end badly, remove the check. Signed-off-by: Nick Bowler <nbowler@elliptictech.com> Signed-off-by: David S.
