[dpdk-dev] [PATCH v6 3/3] app/testpmd: handle device recovery event

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Kalesh AP <kalesh-anakkur.purayil@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.

Updated 20.11 release notes as well.
