4.2 TCP, large packets and pronet-drivers

[dave at uwvax.ARPA]

I got a number of replies to my question.  This one pretty much says
it all:

> Sure, we had this problem.  The problem is that the 4.2 code seems to
> decide randomly whether to use trailers or not (actually, it's not
> random, but I don't understand the algorithm - only large packets
> will be sent with trailers, though...)  If your gateways don't
> understand trailer protocols (as ours don't), then the large
> packets sent with trailers will never get through.

> Our limited experience with trailers was that they made essentially
> no difference in throughput at any time on any type of connection,
> so we just turned them off.
