Merge branch 'geneve-vxlan-deps'
Hannes Frederic Sowa says:
====================
net: network drivers should not depend on geneve/vxlan
This patchset removes the dependency of network drivers on vxlan or
geneve, so those don't get autoloaded when the nic driver is loaded.
Also audited the code such that vxlan_get_rx_port and geneve_get_rx_port
are not called without rtnl lock.
====================
