Hi Sameer,

Thanks for your patience and I apologize for not reaching out yesterday.

Normally, if you want a retest you send an email on your patch requesting
one per the instructions here and it automatically gets picked up by the
Community Lab CI testing system:
https://core.dpdk.org/testing/#requesting-a-patch-retest

In this case I will just trigger the retest directly since I'm the
Community Lab manager. The failure in question should be gone in approx 30
minutes.

Have a good weekend.
