Subject: [PATCH 3.13 046/187] bnx2x: Adapter not recovery from EEH error injection

3.13.11.7 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "wenxiong@...ux.vnet.ibm.com" <wenxiong@...ux.vnet.ibm.com>

commit 0c0e63410a393aae4b615849625f539db775d586 upstream.

When injecting EEH error to bnx2x adapter, adapter couldn't be recovery
and caused recursive EEH errors. The patch fixes the issue.
