[dpdk-dev] [PATCH v3 0/3] Keep-alive enhancements

[Remy Horton]

This patchset adds enhancements to the keepalive core monitoring and
reporting sub-system. The first is support for idled (sleeping and
frequency-stepped) CPU cores, and the second is support for applications
to be notified of active as well as faulted cores. The latter is to allow
core state to be relayed to external (secondary) processes, which is
demonstrated by changes to the l2fed-keepalive example.
