Comment (by rmilecki):
A bit more of research.
1. During the first try (in `bridge_config_init`) adding `eth0` to the
`br-lan` fails, because kernel refuses it.\\The call trace looks more or
less like this:
{{{
dev_ifsioc(?, ?, SIOCBRADDIF) [ifr->ifr_name is "br-lan"]
br_dev_ioctl(?, ?, SIOCBRADDIF)
add_del_if(?, ?, true)
br_add_if(?, ?)
netdev_master_upper_dev_link(?, ?)
__netdev_upper_dev_link
return -EEXISTS
}}}
2. Then there is something **removing** interface:
{{{
dev_ifsioc(?, ?, SIOCBRDELIF) [ifr->ifr_name is "br-lan"]
br_dev_ioctl(?, ?, SIOCBRDELIF)
add_del_if(?, ?, false)
(...)
}}}
3. Finally netifd runs `bridge_retry_members` and tries to add interfaces
to the `br-lan`. But it fails because such a bridge doesn't exist anymore.
{{{
dev_ifsioc(?, ?, ?)
dev = __dev_get_by_name(?, "br-lan")
return NULL
return -ENODEV
}}}
