[Xen-users] xen vif bug

[Tony Hoyle <tmh@xxxxxxxxxxxx>]

Hi,

Is this the best place to report a bug?

I accidentally wrote the following in a config file:

vif         = [ 'mac==aa:00:f4:77:74:1e' ]

The == caused the network driver to oops!  Some sanity check missing
somewhere..

I've confirmed that removing the == and using the exact same 
configuration otherwise does not cause the bugcheck.
kernel BUG at net/core/dev.c:3326!
