svn commit: r208120 - head/sys/dev/bwn

[Weongyo Jeong]

Author: weongyo
Date: Sat May 15 21:18:15 2010
New Revision: 208120
URL: http://svn.freebsd.org/changeset/base/208120

Log:
  - fixes a bug that it didn't initialize the ratectl after association;
    so ni_txrate returned 0 which is a invalid result.
  - The fourth argument of ieee80211_ratectl_tx_complete() could be not
    NULL.
