Subject: [PATCH net-next v2 4/6] selftests: net: py: avoid all ports < 10k

From: Jakub Kicinski <[email-masked]>
Date: Mon, 29 Apr 2024 07:44:24 -0700

When picking TCP ports to use, avoid all below 10k.
This should lower the chance of collision or running
afoul whatever random policies may be on the host.
