Subject: [PATCH net 0/5] net: lan966x: Fix issues with MAC table

The patch series fixes 2 issues:
- when an entry was forgotten the irq thread was holding a spin lock and then
  was talking also rtnl_lock.
- the access to the HW MAC table is indirect, so the access to the HW MAC
  table was not synchronized, which means that there could be race conditions.

Horatiu Vultur (5):
  net: lan966x: Fix taking rtnl_lock while holding spin_lock
  net: lan966x: Fix usage of lan966x->mac_lock when entry is added
  net: lan966x: Fix usage of lan966x->mac_lock when entry is removed
  net: lan966x: Fix usage of lan966x->mac_lock inside
    lan966x_mac_irq_handler
  net: lan966x: Fix usage of lan966x->mac_lock when used by FDB
