Subject: 4.3.0+ breaks software VPN

Hi,

Tried to connect to sw vpn today, and it isn't working. Running git 
as-of yesterday. In dmesg:

[23703.921542] vpn0: set_features() failed (-1); wanted 
0x00000080000048c1, left 0x00000080001b48c9

Reverting:

fd867d51f889
5ba3f7d61a3a
e7868a85e1b2

in reverse order makes it work again. How do we get this fixed so that 
4.4-rc1 doesn't break basic VPN support?
