Moderate ethernet traffic causes "soverflow for fx->in" to be printed to the screen on vmware 3.1.0. Examples are using upas/fs to get a imap mailbox of a few hundred messages and doing a pull from sources where a lot has changed. Without this patch both these examples fail.

This patch comments out the first print in /sys/src/9/pc/devether.c that causes this message to appear. The examples then succeed. This was done following advice from Erik Quanstrom.

    I think we want to leave this in.  If you're seeing
    the message, something is wrong and ought to be investigated.
