Hi Broadcom developers and linux wireless list.

We found a possible issue in the cfg80211 implementation of the regulatory domain rules:

        .reg_rules = {
                /* IEEE 802.11b/g, channels 1..11 */
                REG_RULE(2412-10, 2472+10, 40, 6, 20, 0),


the referred channel 11 has/should have a frequency of 2462, not 2472 (corresponding to channel 13).
Is this a typo in the code or the above comment?

(I'm not sure why the override of reg.c is in place for 2.4 Ghz frequencies)

Can you please double check and in case apply the attached patch?

thanks,

 11 is actually 2462, not 2472 (that is channel 13 instead)
