From aa790db9a7a3a9591f4d5ba0dead00e99dcd9412 Mon Sep 17 00:00:00 2001 From: Padmanabh Ratnakar Date: Sat, 20 Oct 2012 06:03:25 +0000 Subject: [PATCH] be2net: Fix issues in error recovery due to wrong queue state During recovery from a FW error, destroy queue operation may fail. Queue should be marked as destroyed so that recovery code can recreate the queue. Also fix queue created state not getting checked at one instance.
