Re: ix SR-IOV working

Hello,

This is probably a driver issue. The only way I could get sr-iov
working with the ix driver is compiling the driver provided
by Intel and loading it before boot. [1] for more details and [2]
for the driver. Have not tested the latest version and only
tested this on CURRENT. Also, there were some options that
needed to be changed before compiling to enable sr-iov, it's
pretty straightforward though if I recall correctly.
