From cf2c1df62e065bfc15e38daf2d3479a56b320f29 Mon Sep 17 00:00:00 2001 From: Merav Sicron Date: Tue, 19 Jun 2012 07:48:23 +0000 Subject: [PATCH] bnx2x: Return only online tests for MF 1. In multi-function device, show only the online tests in self-test results as only these test are performed (offline tests cannot be performed as they may corrupt the traffic of other functions on the same physical port). Note that multi-function mode cannot change while the driver is up. 2. Check result code in NIC load and act accordingly.
