[Barrelfish-users] 82599EB NICs not work

[Reto Achermann]

Hi Tom,

We also had some troubles with the e10k. However, we received a patch 
that fixes the initialization of the card. However, the patch has not 
made its way to the release yet.

@Simon: Antoine sent it to Stefan, however w/o sign off.
