2022-09-28net: drop the weight argument from netif_napi_addJakub Kicinski2-5/+2
We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

The problem with this spin lock is that it was just protecting the list of the MAC entries in SW and not also the access to the MAC entries in HW. Because the access to HW is indirect, then it could happen to have race conditions. For example when SW introduced an entry in MAC table and the irq mac is trying to read something from the MAC.

2022-07-18net: lan966x: Fix taking rtnl_lock while holding spin_lockHoratiu Vultur1-9/+18
When the HW deletes an entry in MAC table then it generates an interrupt. The SW will go through it's own list of MAC entries and if it is not found then it would notify the listeners about this. The problem is that when the SW will go through it's own list it would take a spin lock(lan966x->mac_lock) and when it notifies that the entry is deleted. But to notify the listeners it taking the rtnl_lock which is illegal. This is fixed by instead of notifying right away that the entry is deleted, move the entry on a temp list and once, it checks all the entries then just notify that the entries from temp list are deleted.

Instead of counting the child nodes in the device tree, hardcode the number of ports in the driver itself. The counting won't work at all if an ethernet port is marked as disabled, e.g. because it is not connected on the board at all. It turns out that the LAN9662 and LAN9668 use the same switching IP with the same synthesis parameters. The only difference is that the output ports are not connected. Thus, we can just hardcode the number of physical ports to 8.
