From 3e450669cc7060d56d886f53e31182f5fef103c7 Mon Sep 17 00:00:00 2001 From: Peter P Waskiewicz Jr Date: Sat, 7 Feb 2009 02:16:59 -0800 Subject: [PATCH] ixgbe: Fix a set_num_queues() bug that can result in num_(r|t)x_queues = 0 Now that our set_num_queues() routines for each feature are re-entrant, and can be called at any point, they shouldn't zero out the feature's indices or mask bits. Subsequent calls into those routines for those features can result in zero Rx and Tx queues being assigned, causing a panic later in driver reinitialization.
