| possible timeline: | |
| - gets dhcp lease, calls dhcp_lease_acquired | |
| - sets mtu to 9000 (asynchronously, does not fail when the iface is up, may either claim to succeed or fail with the link down) | |
| - calls dhcp4_update_address which then calls address_configure with dhcp4_address_handler | |
| - address_configure builds a rtnl message to configure the link with the dhcp4_address_handler as the callback | |
| - sends that message async | |
| - link goes down, event generated | |
| - link lease cleaned up | |
| - link comes back up | |
| - rtnl sends reply, triggers dhcp4_address_handler which calls link_set_dhcp_routes | |
| - link->lease is bad, causes crash |
