It also adds type safety for netdev-hook.

Moves the registration of the RHEL specific OVS hook to the compat
backport of netdev_rx_handler_register(). This moves the hook
unregistration from the RCU callback to the netdev_destroy()
callback directly.
This is purely cosmetic though, the RHEL hook is only used if the
IFF_OVS_DATAPATH flag is present which was removed under RTNL
protection before the RCU callback.

Explicitly check the availability of several kernel API functions
instead of relying on the kernel version to account for Red Hat
Enterprise Linux backports.

Currently ovs is using device stats for Linux devices and count them
itself in other situations. This leads to overlap with hardware stats,
inconsistencies, etc. It's much better to just always count the packets
flowing through the switch and let userspace do any merging that it wants.
Following patch removes vport->get_stats() interface. vport-stat is changed
to use new `struct ovs_vport_stat` rather than rtnl_link_stats64.
Definitions of rtnl_link_stats64 is removed from OVS. dipf_port->stat is also
removed as aggregate stats are only available at netdev layer.

Currently the kernel vlan actions mirror those used by OpenFlow 1.0.
i.e. MODIFY and STRIP. More flexible approach is to have an action to
push a tag and pop a tag off, so that it can handle multiple levels of vlan
tags. Plus it aligns with newer version of OpenFlow.
As this patch replaces MODIFY with PUSH semantic, action
mapping done in userpace is fixed accordingly.
GSO handling for multiple levels of vlan tags is also added as
Jesse suggested before.

The linux-2.6 and compat-2.6 directories apply equally to the upcoming
Linux 3.0 release, so this drops the 2.6 suffix and updates Makefiles.
