lxtphy attaches where ukphy does now.  At Bernd Ernesti's suggestion
I removed lxtphy from the config.  Symptoms are the same with either
phy.

% ifconfig tl0 inet 192.168.234.134 netmask 0xffffff00 media auto

% tcpdump -i tl0
...sees packets with the second configuration (100baseTX).

Specifying "instance 0" on the ifconfig with "media auto" produces
identical output to the first configuration.

....
