  3e77f70e7345 ("can: dev: move driver related infrastructure into separate subdir")
  0a042c6ec991 ("can: dev: move netlink related code into seperate file")

  Code move.

drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c
  57ac4a31c483 ("net/mlx5e: Correctly handle changing the number of queues when the interface is down")
  214baf22870c ("net/mlx5e: Support HTB offload")

  Adjacent code changes

net/switchdev/switchdev.c
  20776b465c0c ("net: switchdev: don't set port_obj_info->handled true when -EOPNOTSUPP")
  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.
