  Code move.

  57ac4a31c483 ("net/mlx5e: Correctly handle changing the number of queues when the interface is down")
  214baf22870c ("net/mlx5e: Support HTB offload")

  Adjacent code changes

  ffb68fc58e96 ("net: switchdev: remove the transaction structure from port object notifiers")
  bae33f2b5afe ("net: switchdev: remove the transaction structure from port attributes")

  Transaction parameter gets dropped otherwise keep the fix.
