Author: sam Date: Thu Feb 19 05:28:03 2009 New Revision: 188784 URL: http://svn.freebsd.org/changeset/base/188784 Log: Fixup handling of roaming and xmit parameters to support 1/2 and 1/4-width channel modes: o usurp 'h' mode flag for half-width channels o add 'q' mode flag for quarter-width channels o rewrite rate parameter parsing to handle fractional values o merge mode loops to eliminate ordering assumptions o replace 0x80 with IEEE80211_RATE_MCS Modified: head/sbin/ifconfig/ifieee80211.c Modified: head/sbin/ifconfig/ifieee80211.c ============================================================================== --- head/sbin/ifconfig/ifieee80211.c Thu Feb 19 05:22:40 2009 (r188783) +++ head/sbin/ifconfig/ifieee80211.c Thu Feb 19 05:28:03 2009 (r188784) @@ -126,9 +126,19 @@ static void LINE_INIT(char c);
