Not sure if DCCP might fall into this category as well...
I think the idea of this patch is gather some number of these small packets and
shove them at the driver in one go instead of each small packet at a time.
This reminds me... (rick starts waxing rhapshodic about old HP-UX behviour :)
The HP-UX drivers have a "packet train" mode whereby IP will give them all the
fragments of an IP datagram in one shot. The idea was that the driver would
take all of them, or none of them. This was to deal with issues around filling
a driver's transmit queue with some of the fragments and then dropping the
others, thus transmitting IP datagrams which had no hope of being reassembled
into anything other than frankengrams.
