From c6cc1ca7f4d70cbb3ea3a5ca163c5dabaf155cdb Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Tue, 1 Sep 2015 09:24:25 -0700 Subject: flowi: Abstract out functions to get flow hash based on flowi Create __get_hash_from_flowi6 and __get_hash_from_flowi4 to get the flow keys and hash based on flowi structures. These are called by __skb_get_hash_flowi6 and __skb_get_hash_flowi4. Also, created get_hash_from_flowi6 and get_hash_from_flowi4 which can be called when just the hash value for a flowi is needed.
