Subject: ah: Don't return NET_XMIT_DROP on input.
From: Nick Bowler <[email protected]>
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.
