[Barrelfish-users] e1000 driver for final review and Barrelfish merge if accepted.

[Pravin]

Hi Mateusz,

It seems lot of functionality, and I will be glad to review your patch
and work on getting it into streamline :-)

Currently I am swamped with few other things, and as soon as I get
over them, I will start working on this.

Regards,
Pravin
