Hi all,

This series adds TLS 1.3 hardware offload support including KeyUpdate
(rekey) and a selftest for validation.

Patch 1: Reject TLS 1.3 offload in chcr_ktls and nfp drivers
  These drivers only support TLS 1.2; add explicit version check.

Patch 2: mlx5e TLS 1.3 hardware offload
  Add TLS 1.3 TX/RX offload on ConnectX-6 Dx and newer.
  Handle 12-byte IV format and TLS_1_3 context type.

Patch 3: Core TLS 1.3 hardware offload support
  Extend tls_device.c for TLS 1.3 record format (content type
  appended before tag). Handle TLS 1.3 IV construction in fallback.

Patch 4: Split tls_set_sw_offload into init/finalize
  Allows HW RX path to init SW context, attempt HW setup, then
  finalize. Required for proper rekey error handling.

Patch 5: Hardware offload key update (rekey) support
  Delete old HW context and add new one with updated key.
  Graceful SW fallback if HW rekey fails.
  Track ACKs to ensure old-key data is flushed before HW switch.

Patch 6: Selftest for hardware offload
  Python wrapper + C binary using NetDrvEpEnv framework.
  Tests TLS 1.2/1.3, AES-GCM-128/256, rekey, various buffer sizes.

Tested on Mellanox ConnectX-6 Dx (Crypto Enabled) with TLS 1.3 AES-GCM-128/256
and multiple rekey cycles.
