Here is the summary with links:
  - [v3,net,1/2] net: enetc: read TSN capabilities from port register, not SI
    https://git.kernel.org/netdev/net/c/8e00072c31e2
  - [v3,net,2/2] net: enetc: Do not configure preemptible TCs if SIs do not support
    https://git.kernel.org/netdev/net/c/b2420b8c81ec

You are awesome, thank you!
