`AddressRandomization=network` made iwd present a per-SSID random MAC
to every Wi-Fi network. On networks that pin DHCP leases or 802.1X
access to a specific hardware MAC (corporate Wi-Fi, routers with DHCP
reservations, MAC-filtered networks) this means iwd associates fine
but DHCP never completes — the new MAC is unknown to the upstream.
The privacy gain is marginal when the user only connects to a small
set of known APs anyway, and the cost (no IP on a familiar network)
is much worse than the threat model justified. Drop the override
entirely; iwd's defaults (permanent MAC, no IP config — systemd-networkd
remains the IP-layer authority via etc/systemd/network/30-wifi-bond0.network)
match what we actually want.
If we want privacy MAC again later, the right place is a systemd .link
file with MACAddressPolicy=random, applied per-interface, not iwd-wide.
