Nice. Thanks.

The new serie is available in branch 'netdev-ipg' at
git://electric-eye.fr.zoreil.com/home/romieu/linux-2.6.git

Former branch 'netdev-ipg' was moved to 'netdev-ipg.log'.

I have added a new patch (see (way) below).

$ git log master..

commit 17adeb85054a693224a2ab7787a224c722bdd4eb
Author: Francois Romieu <romieu@fr.zoreil.com>
Date: Fri May 5 01:42:12 2006 +0200

ip1000: ethtool {get/set}_settings support

The patch shoehorns the driver into the usual mii/ethtool framework.
mii_mutex will prove useful when the link management tasks issued in
irq context are moved to user/workqueue context. Next step.

At least the current code should not be _too_ broken.

ip1000: leaks in ipg_probe

The error paths are badly broken.

Bonus:
- remove duplicate initialization of sp;
- remove useless NULL initialization of dev;
- USE_IO_OPS is not used (and the driver does not seem to care about
posted writes, rejoice).

ip1000: speed-up access to the PHY registers

Reduce delays when reading/writing the PHY registers so we clock the
MII management interface at 2.5 MHz (the maximum according to the
datasheet) instead of 500 Hz.

ip1000: root_dev removal and PHY initialization

- Remove ether_crc_le() -- use crc32_le() instead.
- No more nonsense with root_dev -- ipg_remove() now works.
- Move PHY and MAC address initialization into the ipg_probe().
It was previously filling in the MAC address on open which breaks
some user space.
- Folded ipg_nic_init into ipg_probe since it was broke otherwise.
