Description dgilbert 1999-07-19 04:20:01 UTC 
tx0 (SMC 10/100 card) truncates skip packets.  This may have something
to do with the bug in my previous pr, but it is not solved by
removing the 'EARLY_RX' define --- which makes me uncomfortable in
general.

When skip is enabled, a tcpdump on another machine on the same ethernet
will show 'truncated packet' for each ping packet that the host
is trying to return.

Fix: 

I have had to replace tx0 cards with other cards to use skip.
How-To-Repeat: 
Configur and install /usr/ports/security/skip on two machines, one of
which has a tx0.  Ping in either direction while a third host
watches the ethernet.  You will see 'truncated' packets.

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?

Originator is unable to test on a newer version of FreeBSD.  If this 
is still a problem in a newer release of FreeBSD, a new PR should be 
opened.
