Re: [PATCH net v2] selftests/net: fix out-of-order delivery of FIN in gro:tcp test

Anubhav Singh wrote:

Due to the gro_sender sending data packets and FIN packets in very quick succession, these are received almost simultaneously by the gro_receiver. FIN packets are sometimes processed before the data packets leading to intermittent (~1/100) test failures.

This change adds a delay of 100ms before sending FIN packets in gro:tcp test to avoid the out-of-order delivery. The same mitigation already exists for the gro:ip test.
