Allocate FIFO address before registering net_device.
This is preparation to change the pseudo hardware address format
for firewire devices to include the offset of the FIFO for receipt
of unicast datagrams, instead of mangling ARP/NDP messages in the
driver layer.

Following patch series restructure GRE and IPIP tunneling code
to make it modular. It adds ip_tunnel module which acts as
generic tunneling layer which has common code.

These patches do not change any functionality.
v3:v4:
 - Fixed compilation error in ipv6.
 - Few coding style fixes.
v2-v3:
 - Use GPL exports for all export symbols.
 - Set default config NET_IP_TUNNEL to m.

Following patch refactors GRE code into ip tunneling code and GRE
specific code. Common tunneling code is moved to ip_tunnel module.
ip_tunnel module is written as generic library which can be used
by different tunneling implementations.

ip_tunnel module contains following components:
 - packet xmit and rcv generic code. xmit flow looks like
   (gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out.
 - hash table of all devices.
 - lookup for tunnel devices.
 - control plane operations like device create, destroy, ioctl, netlink
   operations code.
 - registration for tunneling modules, like gre, ipip etc.
 - define single pcpu_tstats dev->tstats.
 - struct tnl_ptk_info added to pass parsed tunnel packet parameters.

This patch adds a dev_addr_genid for IPv6. The goal is to use it, combined with
dev_base_seq to check if a change occurs during a netlink dump.
If a change is detected, the flag NLM_F_DUMP_INTR is set in the first message
after the dump was interrupted.

Note that only dump of unicast addresses is checked (multicast and anycast are
not checked).

This patch is meant to be a follow-up for a patch originally submitted under
the title "ioat: Do not enable DCA if tag map is invalid".  It was brought to
my attention that the preferred approach for BIOS workarounds is to set the
taint flag for TAINT_FIRMWARE_WORKAROUND for systems that require BIOS
workarounds.

This change makes it so that the DCA workarounds for broken BIOSes will now
use WARN_TAINT_ONCE(1, TAINT_FIRMWARE_WORKAROUND, ...) instead of just
printing a message via dev_err.
