Subject: [PATCH net 3/5] bnx2x: Fix Duplex setting for 54618se
Date: Wed, 1 Jan 2014 11:06:43 +0200 [thread overview]
Message-ID: <1388567205-20210-4-git-send-email-yanivr@broadcom.com> (raw)
In-Reply-To: <1388567205-20210-1-git-send-email-yanivr@broadcom.com>
BCM54618SE is used to advertise half-duplex even if HD was not requested by the
user. This change makes the legacy speed/duplex advertisement for this PHY
exactly according to the requested speed and duplex.
