In your patch, the first chunk of data (which is handed back to the
nic outside of rtl8169_xmit_frags) will not have is First fragment
bit set when nr_frags != 0. It makes me a bit nervous.

The NPQ part of your patch actually forces the start_xmit handler to
wait for all previously queued packets to be sent before telling the
nic that a packet may be available. I can understand that it will fix
the symptoms but it will implicitly shorten the TX queue a lot.

A pesky fever apart, I should be able to come with a patch before
the week end.
