Merge branch 'sparx5-mrouter'

Casper Andersson says:

====================
net: sparx5: add mrouter support

This series adds support for multicast router ports to SparX5. To manage
mrouter ports the driver must keep track of mdb entries. When adding an
mrouter port the driver has to iterate over all mdb entries and modify
them accordingly.

v2:
- add bailout in free_mdb
- re-arrange mdb struct to avoid holes
- change devm_kzalloc -> kzalloc
- change GFP_ATOMIC -> GFP_KERNEL
- fix spelling
====================
