From 877d1f6291f8e391237e324be58479a3e3a7407c Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Tue, 28 Jul 2015 16:02:05 -0700 Subject: net: Set sk_txhash from a random number This patch creates sk_set_txhash and eliminates protocol specific inet_set_txhash and ip6_set_txhash. sk_set_txhash simply sets a random number instead of performing flow dissection. sk_set_txash is also allowed to be called multiple times for the same socket, we'll need this when redoing the hash for negative routing advice.
