[patch net-next 00/16] net: introduce upper device lists and remove dev->master

[Jiri Pirko <jiri@resnulli.us>]

Hi all.

Recent discussion around
"[net-next] bonding: don't allow the master to become its slave"
forced me to think about upper<->lower device connections.

This patchset adds a possibility to record upper device linkage.
All upper<->lower devices are converted to use this mechanism right after.
That leads to dev->master removal because this info becomes redundant since
"unique links" have the same value.

After all changes, there is no longer possible to do:
"bond->someotherdevice->samebond"

Also I think that drivers like cxgb3, qlcnic, qeth would benefit by this
in future by being able to get more appropriate info about l3 addresses.

Jiri Pirko (16):
  net: introduce upper device lists
  macvlan: add link to upper device
  vlan: add link to upper device
  rtnetlink: remove usage of dev->master
  team: remove usage of netdev_set_master()
  bridge: remove usage of netdev_set_master()
  netpoll: remove usage of dev->master
  cxgb3: remove usage of dev->master
  qlcnic: guard __vlan_find_dev_deep() by rcu_read_lock
  qeth: ensure that __vlan_find_dev_deep() is called with rcu_read_lock
  vlan: remove usage of dev->master in __vlan_find_dev_deep()
  nes: remove usage of dev->master
  bonding: remove usage of dev->master
  net: remove no longer used netdev_set_bond_master() and
    netdev_set_master()
  net: remove usage of dev->master
  net: kill dev->master
