Endless loop with 'wpa_cli -g /var/run/wpa_supplicant_if_wiphy0'

[Ben Greear]

While trying to figure out how to get wpa-cli related events, I notice
that if I start wpa_cli like this:

[root at lf0350-7220 lanforge]# wpa_cli -g /var/run/wpa_supplicant_if_wiphy0
wpa_cli v2.7-devel-hostap_2_3-5027-gd3f2ce9+

Then, the supplicant logs spam endlessly:

I saw a LEDE patch that appeared to try to hack around this or a similar issue, but I guess
that never made it upstream.

Any suggestions for the proper way to fix this?

Thanks,
Ben
