Subject: [PATCH] ethtool: Do not report link partner advertising flags if set to 0
Date: Sun, 20 Dec 2009 19:12:30 +0000	[thread overview]
Message-ID: <1261336350.25157.200.camel@localhost> (raw)

Only some drivers (and none before kernel version 2.6.31) currently
set these flags.  When the flags are equal to 0 and so we don't know
what the link partner advertised, don't report anything.
