Symbolics support of Ethernet trailers

[Barry Margolin <barmar@THINK.COM>]

Has anyone modified the Symbolics Ethernet drivers to allow reception of
Ethernet packets with trailers?  When setting up new Ultrix machines, we
often forget to specify "-trailers" in their /etc/rc.local scripts, and
later on users start losing when they try to communicate with Lispms.  I
don't see any need for Lispms to SEND trailers, nor even to acknowledge
the ability to use them if the Unix machine tries trailer negotiation
(as 4.3bsd and I think SunOS 3.2 do), but it would be nice if they
could receive them if a machine inadvertently sends them.
