Build Update for david-marchand/ovs
-------------------------------------

Build: #94
Status: Broken

Duration: 1 hr, 21 mins, and 20 secs
Commit: 2a35950 (master)
Author: David Marchand
Message: dpdk: Support running PMD threads on cores > RTE_MAX_LCORE.

Most DPDK components make the assumption that rte_lcore_id() returns
a valid lcore_id in [0..RTE_MAX_LCORE] range (with the exception of
the LCORE_ID_ANY special value).

OVS does not currently check which value is set in
RTE_PER_LCORE(_lcore_id) which exposes us to potential crashes on DPDK
side.

Introduce a lcore allocator in OVS for PMD threads and map them to
unused lcores from DPDK à la --lcores.

The physical cores on which the PMD threads are running still
constitutes an important information when debugging, so still keep
those in the PMD thread names but add a new debug log when starting
them.

Synchronize DPDK internals on numa and cpuset for the PMD threads by
registering them via the rte_thread_set_affinity() helper.

Existing users of dpdk-lcore-mask will benefit from this transparently.
