[dpdk-dev] [PATCH v6 00/11] al: replace calls to rte_panic and refrain from new instances

Hi,

What happened to this patchset?

This is definitely an improvement. We must remove rte_panic from libs.
Arnon, are you still available to rebase this patchset in preparation
of 19.08? Or someone else?

What are the required API breakages? I see one in ethdev which requires
a deprecation notice to be sent for publishing in 19.05.

Is there more rte_panic to remove?
