From 02481bc678076f05643e7b240b2ea7c9aa1e72e1 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 6 Aug 2013 15:50:07 -0700 Subject: [PATCH] bnx2: Handle error condition in ->slot_reset() by closing the device if necessary. Otherwise, since NAPI state is already disabled, a subsequent close will hang the system. Signed-off-by: Michael Chan Signed-off-by: David S.
