I just noticed that if you change the MTU of a tg3 NIC, it will not work
untill you ifdown/ifup it.  This problem is repeatable on tg3, and does not
happen with the e1000 driver/cards.

I am setting the MTU via an ioctl call, not via ifconfig or something like
that.


Can you provide the ioctl call info, so I can reproduce?

And, are you changing MTU when the interface is up or down?
