What are you doing with those? > +#define IS_CH_5G_BAND_MID(channel) \ > + (IS_CH_5G_BAND_2(channel) || IS_CH_5G_BAND_3(channel)) > + > +#define IS_CH_2G_BAND(channel) ((channel) <= 14) > +#define IS_CH_5G_BAND(channel) \ > + (IS_CH_5G_BAND_1(channel) || IS_CH_5G_BAND_2(channel) || \ > + IS_CH_5G_BAND_3(channel) || IS_CH_5G_BAND_4(channel)) Given the above (you have major holes in 5G_BAND{1,2,3,4}), this macro seems like a regression.
