Subject: [PATCH 0/3] Remove IPVlan module dependencies on IPv6 and Netfilter

The IPVlan module currently depends on IPv6 and Netfilter.
Refactor the code to allow building IPVlan module regardless of the value of
CONFIG_IPV6 and CONFIG_NETFILTER.
Also change the dependency to CONFIG_NET_L3_MASTER_DEV into a select,
as compiling L3 Master device alone has no sense.

$ grep -wE 'CONFIG_(IPV6|NETFILTER|IPVLAN)' .config
CONFIG_IPV6=y
CONFIG_NETFILTER=y
CONFIG_IPVLAN=m
$ ll drivers/net/ipvlan/ipvlan.ko
48K drivers/net/ipvlan/ipvlan.ko

$ grep -wE 'CONFIG_(IPV6|NETFILTER|IPVLAN)' .config
# CONFIG_IPV6 is not set
CONFIG_NETFILTER=y
CONFIG_IPVLAN=m
$ ll drivers/net/ipvlan/ipvlan.ko
44K drivers/net/ipvlan/ipvlan.ko

$ grep -wE 'CONFIG_(IPV6|NETFILTER|IPVLAN)' .config
CONFIG_IPV6=m
# CONFIG_NETFILTER is not set
CONFIG_IPVLAN=m
$ ll drivers/net/ipvlan/ipvlan.ko
46K drivers/net/ipvlan/ipvlan.ko

$ grep -wE 'CONFIG_(IPV6|NETFILTER|IPVLAN)' .config
# CONFIG_IPV6 is not set
# CONFIG_NETFILTER is not set
CONFIG_IPVLAN=m
$ ll drivers/net/ipvlan/ipvlan.ko
43K drivers/net/ipvlan/ipvlan.ko

Matteo Croce (3):
  ipvlan: drop ipv6 dependency
  ipvlan: drop netfilter dependency
  ipvlan: selects master_l3 device instead of depending on it
