From 3bb62f4f95ba004048bafb460179b5db33aff787 Mon Sep 17 00:00:00 2001 From: Padmanabh Ratnakar Date: Fri, 25 Nov 2011 05:48:06 +0000 Subject: [PATCH] be2net: Fix error recovery paths When TX queues are created again after error recovery, netif_set_real_num_tx_queues() is invoked to update number of real TX queues created. rtnl lock needs to be held when invoking this routine.
