Subject: [PATCH net-next 0/2] xfrm: IPsec hardware offload performance improvements

This patch series optimizes IPsec crypto offload performance by
addressing a lock contention bottleneck using RSS.

The first patch refactors the xfrm_input to avoid a costly
unlock/relock cycle.

The second patch builds on this by removing a redundant replay check,
which is unnecessary for the synchronous hardware path.

Jianbo Liu (2):
  xfrm: Refactor xfrm_input lock to reduce contention with RSS
  xfrm: Skip redundant replay recheck for the hardware offload path
