Hi all again I'm going to reply myself Tigon3 driver, at least until 2.2 version, as it can't be downloaded from http://people.redhat.com/jgarzik/tg3/tg3-2.2/tg3.c doesn't support the settings I was talking about, so ethtool is fine (I looked at the source code & compared with other drivers) I previously supossed (wrong) It must support the feature because a previous comment that was posted in this mailing list some time ago Ulisses On Tue, Jan 27, 2004 at 05:29:42PM +0100, uaca@alumni.uv.es wrote: > > Hi all > > I'm using a tigon3 with 2.6.1 vanilla (lspci -vv and /proc/interrupts at the
