[B.A.T.M.A.N.] [PATCH-next 1/3] net: propagate upper priv via netdev_master_upper_dev_link

[Sven Eckelmann]

From: Jiri Pirko <jiri@mellanox.com>

Eliminate netdev_master_upper_dev_link_private and pass priv directly as
a parameter of netdev_master_upper_dev_link.

[B.A.T.M.A.N.] [PATCH-next 2/3] net: add possibility to pass information about upper device via notifier

[Sven Eckelmann]

From: Jiri Pirko <jiri@mellanox.com>

Sometimes the drivers and other code would find it handy to know some
internal information about upper device being changed. So allow upper-code
to pass information down to notifier listeners during linking.

[B.A.T.M.A.N.] [PATCH-next 3/3] batman-adv: Act on NETDEV_*_TYPE_CHANGE events

[Sven Eckelmann]

From: Andrew Lunn <andrew@lunn.ch>

A network interface can change type. It may change from a type which
batman does not support, e.g. hdlc, to one it does, e.g. hdlc-eth.
When an interface changes type, it sends two notifications. Handle
these notifications.
