From d6ea7c9ccc9fd351fa2675304695d1654331fca3 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 19 Jul 2010 13:59:27 +0000 Subject: [PATCH] ixgbe: drop support for UDP in RSS hash generation This change removes UDP from the supported protocols for RSS hashing. The reason for removing this protocol is because IP fragmentation was causing a network flow to be broken into two streams, one for fragmented, and one for non-fragmented and this in turn was causing out-of-order issues.
