Yup, doesn't seem to be used anywhere; the file also has some coding
style issues, so perhaps removing the macro can be part of a cleanup
patch for whoever may carry out that task.

In that case, I guess reverting the patch from staging-next might be an
option, but I think what's really needed is for someone to go through
the driver source and do what's necessary... At first glance, it seems
possible that the macro (NUM_RULES) may indeed have to be used as a 
replacement for the hard-coded CB_MAX_CHANNEL, but the author may not 
have gotten around to it or didn't make use of it for some other reason.

[PATCH 8/8] net/wireless: use ARRAY_SIZE macro in radiotap.c

[Nikitas Angelinas]

Replace sizeof(rtap_namespace_sizes) / sizeof(rtap_namespace_sizes[0])
with ARRAY_SIZE(rtap_namespace_sizes) in net/wireless/radiotap.c
