From 163de42e240623694562656542adedbca369beaf Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 7 May 2009 10:39:16 +0000 Subject: [PATCH] ixgbe: set queue0 for srrctl configuration correctly for DCB The current configuration is not setting queue 0 correctly for DCB configurations. As a result unconfigured queues are being used to setup the SRRCTL register rx buffer len sizes. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
