usb_ethersubr.h
Log:
Apply the same netisr mechanism to transmissions as well. In order to
drive the transmitter, we have to check the interface's send queue in the
TX end of frame handler (i.e. the usb bulk out callback) and push out new
transmissions if the queue has packets in it and the transmitter is
ready. But the txeof handler is also called from a USB callback running
at splusb() too.
Grrr.
