Hello,

=20

You did not understand the purpose of that parameter, it is made to =
=91avoid=92
nic_uio from pursuing the wanted NICs... so they are free to be used in =
the
system :)

Right now the code to handle it is wrong and I am trying to fix it =
myself.

Hi,

I tried with Intel version 1.6.0 and FreeBSD 9.2-RELEASE on VMware =
Player.

kldload nic_uio by hand, works fine.
But kldunload nic_uio only detach uio driver, don't re-attach kernel =
driver.

Hi, guys.



This variable is not working as intended for FreeBSD :(



It does not dettach nic_uio from the wanted ports :/
