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

Build: #288
Status: Failed

Duration: 33 mins and 36 secs
Commit: e13a41d (dpdk-latest-external-lcores)
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.

Make use of the new dpdk API to register external threads.

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.
DPDK lcores can be dumped with a new dpdk/dump-lcores command.
