From a0c2c19093bb326ecce4231e558f92e1e7985e37 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 1 Sep 2008 12:45:08 +0100 Subject: [PATCH] sfc: Avoid mangling error codes in efx_test_loopback() efx_test_loopback() used "|" to combine the results of the RX and TX phases. If both phases fail with different error codes, this results in a bogus error code.
