Subject: [PATCH v2 net-next 0/2] net: RPS table overwrite prevention and flow_id caching
Date: Tue, 15 Jul 2025 16:54:29 +0530	[thread overview]
Message-ID: <20250715112431.2178100-1-krikku@gmail.com> (raw)

This series splits the previous RPS patch [1] into two patches
targeting net-next as per reviewer feedback.

The first patch prevents RPS table overwrite for active flows thereby
improving aRFS stability.

The second patch caches hash & flow_id in get_rps_cpu() to avoid
recalculating it in set_rps_cpu() (this patch depends on the first).
