Message-ID: <1399362409-17039-2-git-send-email-rajesh.borundia@qlogic.com> Date: Tue, 6 May 2014 03:46:48 -0400 From: Rajesh Borundia <rajesh.borundia@...gic.com> To: <davem@...emloft.net> CC: <netdev@...r.kernel.org>, <Dept-HSGLinuxNICDev@...gic.com>, Manish Chopra <manish.chopra@...gic.com> Subject: [PATCH net 1/2] qlcnic: Fix panic while dumping TX queues on TX timeout From: Manish Chopra <manish.chopra@...gic.com> o In case of non-multi TX queue mode driver does not initialize "crb_intr_mask" pointer and driver was accessing that un-initialized pointer while dumping TX queue. So dump "crb_intr_mask" only when it is initilaized.
