New Revision: 218789
URL: http://svn.freebsd.org/changeset/base/218789
Log:
Remove use case of DC_TX_ONE. It was used to limit queue just 1 TX
frame in DM910x controllers. In r67595(more than 10 years ago) it
was replaced to use "Store and Forward" mode and made controller
generate TX completion interrupt for every frame.
