The current regulatory code on cfg80211 performs a check to see if a regulatory rule belongs to an IEEE band so that if a Country IE is received and no rules are specified for a band (which is allowed by IEEE) those bands are left intact. The current band check assumes a rule is bound to a band if the rule's start or end frequency is less than 2 GHz apart from the center of frequency being inspected. In order to support 60 GHz for 802.11ad we need to increase this to account for the channel spacing of 2160 MHz whereby a channel somewhere in the middle of a regulatory rule may be more than 2 GHz apart from either the beginning or end of the frequency rule. Without a fix for this even though channels 1-3 are allowed world wide on the rule (57240 - 63720 @ 2160), channel 2 at 60480 MHz will end up getting disabled given that it is 3240 MHz from both the frequency rule start and end frequency. Fix this by using 2 GHz separation assumption for the 2.4 and 5 GHz bands but for 60 GHz use a 10 GHz separation before assuming a rule is not part of the band. Since we have no 802.11ad drivers yet merged this change has no impact to existing Linux upstream device drivers. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Acked-by: Luis R.
