That's remarkably close to 1s.  This often indicates that the transmit
of your next packet is causing the receive buffer to empty.  This is
usually due to blocked interrupts, or a failure to enable interrupts.


But I observe ever increasing counts for the device in /proc/interrupts. So the interrupts are working somewhat.
