From fdd3d631cddad20ad9d3e1eb7dbf26825a8a121f Mon Sep 17 00:00:00 2001 From: Krishna Kumar Date: Wed, 3 Feb 2010 13:13:10 +0000 Subject: [PATCH] ixgbe: Fix return of invalid txq a developer had complained of getting lots of warnings: "eth16 selects TX queue 98, but real number of TX queues is 64" http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg02200.html As there was no follow up on that bug, I am submitting this patch assuming that the other return points will not return invalid txq's, and also that this fixes the bug (not tested).
