From bfcb014b3b18dce0e3f744b0ad919eef47b9d25d Mon Sep 17 00:00:00 2001 From: Jeff Kirsher Date: Wed, 6 Sep 2006 09:38:39 -0700 Subject: ethtool v5: add autoneg advertise feature adds the ability to change the advertised speed and duplex for a network interface. Previously, a network interface was only able to advertise all supported speed's and duplex's, or one individual speed and duplex. The feature allows the user to choose which supported speed's and duplex's to advertise by using the hex value.
