Currently he_support is set only for AP mode. Storing this
information for mesh bss as well helps driver to determine
he support. Also save he operation element params in bss
conf so that drivers can access this for any configurations
instead of having to parse the beacon to fetch that info.

Please always capitalize acronyms. I might let you get away with a
lower-case "BSS" since that doesn't actually *mean* anything, but "he"
is actually an English word...
Anyway, since you haven't paid attention to the robot, I'll drop this
one way or the other.

I think these changes are inappropriate. This is a helper function to
build something, not to store the data. Please change the callers
instead.

Hi Johannes,
Sorry for late response..
Thanks for the review.. I have tried to address the review comments
provided and created new series @

Thanks
