+Subject: [PATCH] device: fix IPv4 forwarding not enabled on modem data
+ interfaces
+
+Modem devices implement ready_for_ip_config() to skip the standard IP
+methods (DHCP, shared, link-local) since they handle IP configuration
+via ModemManager bearers.
+
+This also skipped _dev_ipforwarding4_start(), which is responsible for:
+
+ - Enabling forwarding when needed, e.g. when ipv4.method=shared is
+   active elsewhere.
+
+ - Connecting to the SHARING_IPV4_CHANGED signal so forwarding can be
+   retroactively enabled when a shared connection appears later.
+
+As a result, when using a modem as the upstream connection and a Wi-Fi
+hotspot (ipv4.method=shared), forwarding was not enabled on the
+modem's data interface (e.g. qmapmux0.0), breaking IPv4 connection
+sharing.
+
+Fix this by moving _dev_ipforwarding4_start() to the out_devip label
+so it runs for all device types that have an IP ifindex, including
+those that skip standard IP methods.
+
+Guard with an ifindex check so devices that don't yet have a kernel
+link (like OVS internal interfaces) are not affected.
+
+Fixes: 32cbf4c629a3 ('ip: shared: stop using the global forwarding')
