Subject: hostapd: fix "sh: out of range" errors
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=26c26e11a2131e3e07a9322c9bea6dcc107cddad;p=openwrt%2Fstaging%2Faparcar.git

hostapd: fix "sh: out of range" errors

Several variables in hostapd.sh can be used uninitialized in numerical
comparisons, causing errors in logread:

netifd: radio24 (1668): sh: out of range

Set defaults for those variables to silence those errors.

Fixes: b518f07d4b8a ("hostapd: remove ieee80211v option")
Fixes: cc80cf53c50d ("hostapd: add FTM responder support")
Fixes: e66bd0eb0469 ("hostapd: make rrm report independent of ieee80211k setting")
