From ada7c19e6d27bf4bb6a242960ac6e76f9f21cdd7 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 31 May 2013 14:32:55 +0000 Subject: [PATCH] bnx2x: use XPS if possible for bnx2x_select_queue instead of pure hash The bnx2x_select_queue() was using __skb_tx_hash() to select the transmit queue, totally ignoring XPS settings, while XPS can help performance quite significantly, so change the bnx2x_select_queue() to use __dev_pick_tx() instead which will use XPS if configured.
