ovs-numa: Support non-contiguous numa nodes and offline CPU cores.
This change removes the assumption that numa nodes and cores are numbered
contiguously in linux. This change is required to support some Power
systems.
A check has been added to verify that cores are online,
offline cores result in non-contiguously numbered cores.
DPDK EAL option generation is updated to work with non-contiguous numa nodes.
These options can be seen in the ovs-vswitchd.log. For example:
a system containing only numa nodes 0 and 8 will generate the following:
EAL ARGS: ovs-vswitchd --socket-mem 1024,0,0,0,0,0,0,0,1024 \
--socket-limit 1024,0,0,0,0,0,0,0,1024 -l 0
Tests for pmd and dpif-netdev have been updated to validate non-contiguous
numbered nodes.
