New Revision: 301132
URL: https://svnweb.freebsd.org/changeset/base/301132
Log:
urtwn: unbreak CTS-to-self protection mode.
Do not set HWRTSEN bit when CTS-to-self is used; CTS2SELF bit triggers
CTS frame transmission by itself (and it does not work when HWRTSEN bit
is set).
Tested with:
* RTL8188CUS, HOSTAP mode (11g)
* RTL8188EU, STA mode (11g)
