The port offset calculations depend on the protocol family, but, as Adrian noticed, I broke this logic with the commit 5ee31fc1ecdcbc234c8c56dcacef87c8e09909d8 [INET]: Consolidate inet(6)_hash_connect. Return this logic back, by passing the port offset directly into the consolidated function. Signed-off-by: Pavel Emelyanov Noticed-by: Adrian Bunk Signed-off-by: David S.
