Centrino Wireless-N 1000 support is also broken (Re: iwn(4) in -HEAD supporting Centrino Wireless-N 135)

Tue Apr 29 06:28:40 UTC 2014

  Hello,  sorry for too delay reply.

During a holiday week in Japan, I traced changes of if_iwn.

  r258030 broke and its problem were willing to be coverd by r258085,
then slightly modified r258034 with changes from r258035 to r258085
can operate normally.

  r258035 introduced some program structure changes and some breakages.
I cannot chase what is incorrect in r258035.
