Subject:   Setting Intel Pro100B to half duplex
Message-ID:  <199910111823.NAA87799@sir-alan.chem.indiana.edu>

I have an Intel Pro100B which appears to be choosing the wrong automatic
setting - 100Mbit full duplex, instead of half duplex.

I can't find documentation on the options, if any, for flags for the 
the fxp0 driver.  I did a search on www.freebsd.org and on the local
docs, plus looked in the FBSD Handbook.  There appear to be flags
defined in the kernel code for this card but my C is pretty primitive
and I haven't been able to figure out what the correct flags are.

The hardware is an Everex PO-6200, dual PPro, 64MB, Adaptec 2744 with
4 narrow diff SCSI-II drives, Adpatec 2740 with NEC CD-ROM, S3 Virge
video, Pro100B Enet.  I'm runniong 3.3-RELEASE with a kernel compiled
for SMP (works fine), NETATALK, IPX, ccd, bpf.

The same hardware ran 2.2.7 for quite a while, although not SMP.

Symptoms are high error rates, especially inbound, on both 10 and 100Mbit
connections.  samba 2.0.2 and 2.0.5a both lock up under heavy loads (2.0.5a
has been patched as listed in the bugfixes for the ports version of samba.
