Subject: [PATCH net-next 0/4] net/tls: small TX offload optimizations

Hi!

This set brings small TLS TX device optimizations. The biggest
gain comes from fixing a misuse of non temporal copy instructions.
On a synthetic workload modelled after customer's RFC application
I see 3-5% percent gain.

Jakub Kicinski (4):
  net/tls: unref frags in order
  net/tls: use RCU for the adder to the offload record list
  net/tls: remove the record tail optimization
  net/tls: align non temporal copy to cache lines
