Subject: package/wpa_supplicant: Add options to disable more features.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f24dcf4801dd5a345978b26dabdf103970cbf17;p=buildroot.git

package/wpa_supplicant: Add options to disable more features.

Together, they increase the size of the binary by a bit less than a
megabyte.

As a result, make the wpa_supplicant option a menuconfig.
