[dpdk-dev] [PATCH v7 2/4] app/testpmd: handle device recovery event

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

Added code to handle error recovery events in testpmd.
This is an indication from the PMD that it is undergoing
an error recovery and recovered from the error condition.
