Hi Francois:

In 0049-ip1000-switch-to-classical-tx_current-tx_dirty-ring-management.txt:

It is better to Use tx_timeout than the original one.
Thanks for that.

Best Regards,
Jesse Huang

The previous branch for the driver at
git://electric-eye.fr.zoreil.com/home/romieu/linux-2.6.git has been stored
as 'netdev-ipg-20060831.old'. The current one is based on dc709bd and
named 'ipg'.

Nothing will be pushed tomorrow as I have some bugs to review in different
drivers.
