Do not reset TX threshold value whenever xl_init() is called. Instead
the initial threshould is initialized at device attach. Later the
threshold could be increased if encountering a TX underrun error and
the new threshold should be used in xl_init().
From FreeBSD
Tested on quite a few 3c905/B/C/575 adapters.
