From c9fc891f86c062449116fde8826a0ead650e17ac Mon Sep 17 00:00:00 2001 From: Dhananjay Phadke Date: Mon, 21 Jul 2008 19:44:07 -0700 Subject: [PATCH] netxen: mtu, mac, link status changes MAC addr, multicast filters, mtu are set through firmware commands in firmware v4.0.0+ because of virtualization of physical ports. Link status is also read from registers allocated by firmware for each virtual port.
