Woops, set $int before calling!
Pointy-hat-to: me
Do not pass opt1, pass 1 instead.
This fixes dhclient on optional interfaces.
Ticket #970
Backout last commit
Move /tmp/rc.linkup unlink operation into rc.linkup
Transfer rc.linkup over to devd
Only exit linkup when interface is not a dynamic type. Prior we where exiting only if it was DHCP which would bypass linkup events for PPPoE, etc.
Ignore hotplug event on non-dhcp interfaces
Allow plugging and unplugging of ethernet interfaces (and wireless)
Handle ethernet hotplug events correctly
MFC 7172Add rc.linkup script which will be called from devd when starting or stopping a device
