From 11b0bacd717c285c94dbb56505a28434b34f0639 Mon Sep 17 00:00:00 2001 From: Vitaly Bordug Date: Mon, 14 Aug 2006 23:00:29 -0700 Subject: [PATCH] PAL: Support of the fixed PHY This makes it possible for HW PHY-less boards to utilize PAL goodies. Generic routines to connect to fixed PHY are provided, as well as ability to specify software callback that fills up link, speed, etc. information into PHY descriptor (the latter feature not tested so far).
