This patch makes sure that the tx and rx queues are allocated on the NUMA socket
chosen at device initalization time, instead of the NUMA socket 0.

Thread names are occasionally very useful for debugging, but from time to
time we've forgotten to set one. This commit adds the new thread's name
as a parameter to the function to start a thread, to make that mistake
impossible. This also simplifies code, since two function calls become
only one.
This makes a few other changes to the thread creation function:
* Since it is no longer a direct wrapper around a pthread function,
rename it to avoid giving that impression.
* Remove 'pthread_attr_t *' param that every caller supplied as NULL.
* Change 'pthread *' parameter into a return value, for convenience.
The system-stats code hadn't set a thread name, so this fixes that issue.
This patch is a prerequisite for making RCU report the name of a thread
that is blocking RCU synchronization, because the easiest way to do that is
for ovsrcu_quiesce_end() to record the current thread's name.
ovsrcu_quiesce_end() is called before the thread function is called, so it
won't get a name set within the thread function itself. Setting the thread
name earlier, as in this patch, avoids the problem.

This commit makes the netdev-dpdk module signal the change of
etheraddr and mtu by changing the global sequence number and
incrementing its 'change_seq'.

This commit can be seen as a partial revert of commit
da4a619179d (netdev: Globally track port status changes)
by adding the 'change_seq' to 'struct netdev'.

On DPDK packet recv, ovs is given pointer to mbuf which has
information about a packet, for example pointer to data and size.
By moving mbuf to ofpbuf we can let dpdk allocate ofpbuf and
pass that to ovs for processing the packet.

Following patch adds DPDK netdev-class to userspace datapath. Now
OVS can use DPDK port for IO by just configuring DPDK port and then
adding dpdk type port to userspace datapath.
Refer to INSTALL.DPDK doc for further info.
This is based a patch from Gerald Rogers.
