That commit message looks good.

However, this patch changes more. I did not get back on your question
regarding beacon period and dtim. Sorry for that as it means this patch
still need rework. Those values are obtained differently and filled in
by the function brcmf_fill_bss_param() (called in line 2530). When you
do that make sure the subject prefix is 'PATCH v2' iso 'PATCH' (using
git format-patch option --subject-prefix=..) and add a changelog after
your signed-off line as shown below:
