I noticed there is an issue during negotiate vht channels. If both the ap and station support 160mhz, only channels 36,40,44,48,100,104,108,112 can successfully negotiate as 160mhz. If the ap is configured as channels 52,56,60,64,116,120,124,128, the result is 20mhz.
It appears the incorrect
absmacro cause the vht negotiate think certain channel is 80+80 which should be 160. The intel cards don't support 80+80 and thus the driver treat them as 20mhz.The fix is to correct the
absmacro and also use__builtin_absif available
