Subject: [PATCH] tulip
Date: Mon, 8 Jan 2001 15:01:08 +0100 [thread overview]
Message-ID: <20010108150108.F1831@mind.be> (raw)
[-- Attachment #1: Type: text/plain, Size: 244 bytes --]
Hi,
The following patch tries to improve the media autosensing capabilities of the
2.4 tulip driver. Iused Doanld Becker's tulip driver as a basis. I only tested
it on a Digital PWS500a with onboard 21143 chip with MII transceiver.
Peter.
