OpenWrt's wifi-scripts validator rejects any macfilter value other than
"allow"/"deny" outright — confirmed on real hardware, setting
macfilter='disable' puts netifd in a permanent restart crash loop with the
radio stuck down. The only way to disable filtering is to delete the option
entirely. Also guards against pushing an empty whitelist (macfilter='allow'
with zero MACs blocks every client outright) by treating it as equivalent
to "off".
Adds MAC ACL (whitelist/blacklist) read+write support for wireless SSIDs,
mirroring push_radio_channel's UCI write style. Backs the new Global MAC
ACL feature in netOrk.
'wifi reload' only reapplies the running config without physically
changing the channel on many ath9k/ath10k/mt76 hardware+driver
combinations. A full 'wifi' (down + up) cycle is required for channel
changes to take effect.
Also updated the test assertion accordingly.
