Subject: [MAC80211]: move some rate control functions out of ieee80211.c
X-Git-Tag: v2.6.24-rc1~1454^2~856
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff6880892990aece71a3271425dfde35344d51bb;p=linux-2.6

[MAC80211]: move some rate control functions out of ieee80211.c

I think these can go with rate control just as well and it makes
ieee80211.c more readable.
