It's not (quite) as bad as first appears.  Packets for the 3090 are buffered
at the 8232 for a short while, to see if they can be aggregated with other
packets.  Under load, this means that there will be only 1 I/O interrupt on
the 3090 to receive many packets from many different sources.  This helps
quite a bit.
