From 1648a22b16ab05bd99dd8e2f33ca80bbcea60031 Mon Sep 17 00:00:00 2001 From: Vipul Pandya Date: Wed, 26 Sep 2012 02:39:41 +0000 Subject: [PATCH] cxgb4: Inform caller if driver didn't upgrade firmware If a card had already been initialized, on reloading cxgb4 driver firmware required an upgrade but the upgrade did not happen. In that case a mailbox timeout would occur during T4 configuration file stuff. The fix is to let the caller know the firmware was not upgraded so a reset would be issued before starting the T4 config stuff.
