[ovs-dev] [RFC 0/2] dpdk: minor refactor of the initialization step

[Aaron Conole]

Sometimes, DPDK initialization can fail, but ovs-vswitchd will abort in
that case.  When that occurs, ovs-vswitchd will be restarted by the
monitor and immediately abort.  This is rather unfriendly to users, who
would prefer to possibly correct the issue or at least, not have lots of
processes continually spawning.

This series accepts that rte_eal_init() can and does fail for real.  It
reflects the initialization status in the database, as well as adding
the DPDK version (where appropriate).

Submitted as RFC to spawn discussion around the type to reflect for
the initialized information.  Presented here as a boolean - however,
it might be more interesting to be a 'string' and have more elaborate
details (ex: 'failed - ovs_strerror(rte_errno)' or 'uninitialized' or
'initialized').
