That's what I was looking at, too. But you mentioned "latest kernel",
and I have here:
----------------------------
revision 1.20
date: 2002/08/11 11:09:33; author: wd; state: Exp; lines: +369 -42
1. Added support for PHY DP83843BVJE.
2. Added support for PHY DP83846A.
3. Added a timer callback to periodically probe the DP83846A (or any
other chip, it is easy to adapt) for link changes. The delays are
hard-coded, though. Someone could add some configuration
parameters for it, of course! The periods depend on the link
state:
- 1 second when the link is up.
- 100ms when the link is down.
4. Added the standard IOCTL support to manipulate the PHY registers.
5. A bugfix (in fec_restart(), if the flag 'tx_full' is set, it must
be cleared, and the network interface queue needs to be awakened.)
Based on patch by Jean-Denis Boyer <jdboyer@mediatrix.com>, 22 Mar 2002
See http://lists.linuxppc.org/linuxppc-embedded/200203/msg00200.html
----------------------------
For me, latest == top of CVS :-)

The greatest threat towards future is indifference.
