[PATCH net v3 0/3] macsec: Add support for VLAN filtering in offload mode

[Cosmin Ratiu <cratiu@nvidia.com>]

This short series adds support for VLANs in macsec devices when offload
mode is enabled. This allows VLAN netdevs on top of macsec netdevs to
function, which accidentally used to be the case in the past, but was
broken. This series adds back proper support.

netdevsim was extended to support VLANs and there's also a selftest for
the new functionality.

V3:
- Moved back to net.
- Added proper rollback support for VLAN filters in case of failure.
- Added VLAN as a requirement for the new macsec tests.

V2: https://lore.kernel.org/netdev/20260227090227.1552512-1-cratiu@nvidia.com/
- Sent to net-next instead of net because of apparent complexity.
- Changed VLAN filtering to only function in offload mode.
- Added tests.

V1: https://lore.kernel.org/netdev/20260107104723.2750725-1-cratiu@nvidia.com/
