Subject: [PATCH net-next v2 0/2] netdevsim: support setting a permanent
 address

Network management daemons that match on the device permanent address
currently have no virtual interface types to test against.
NetworkManager, in particular, has carried an out of tree patch to set
the permanent address on netdevsim devices to use in its CI for this
purpose.

This series adds support to netdevsim to set a permanent address on port
creation, and adds a test script to test setting and getting of the
different L2 address types.

Changes in v2:
- Set the permanent address on port creation instead of through debugfs
- Add test script for testing L2 address setting and getting
- Link to v1: https://lore.kernel.org/r/20250203-netdevsim-perm_addr-v1-1-10084bc93044@redhat.com
