Public bug reported:
SRU Justification:
[ Impact ]
In densely-populated areas with more than 200 Wi-Fi APs,
wpa_supplicant's default BSS_MAX_COUNT of 200 causes some nearby wi-fi
APs to only appear inconsistently.
In areas with more APs, setting a higher bss_max_count of 500 via
wpa_cli was sufficient to resolve this issue. Since such dense areas are
now common, it may be appropriate to raise the default to 500 or 1000.
[ Test Plan ]
Run an nmcli scan in an area with 500+ APs, with and without the
described wpa_supplicant change. Confirm that the change results in all
expected APs being present.
[ Fix ]
Bump the DEFAULT_BSS_MAX_COUNT to 500
[ Where problems could occur ]
It's conceivable that there could be differences in time required to
scan / enumerate more APs
