From 53edee2cfbcd869371cb720f1c00d85ba7f2566c Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Fri, 24 May 2013 00:59:47 +0000 Subject: [PATCH] bonding: allow xmit hash policy change while bond dev is up Since the xmit_hash_policy pointer is always valid and not dependent on anything, we can change it while the bond device is up and running. The only downside would be the out of order packets but that is a small price to pay. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S.
