- Fix to use multiqueue start/stop APIs
- Change to return NETDEV_TX_BUSY instead of holding the TX skb when busy
- Increase Tx ring size to 128 to address performance issues in some platforms
- Use NAPI_POLL_WEIGHT for Tx Napi handler instead of ring dependent value
- Use multiqueue to register 4 Rx channels

There is no dedicated reset for just the switch core. The reset which
is used up until now, is more of a global reset, resetting almost the
whole SoC and cause spurious errors by doing so. Make it possible to
handle the reset elsewhere and make the reset optional.

Extend MAC support to support also lag interfaces:
1. In case an entry is learned on a port that is part of lag interface,
then notify the upper layers that the entry is learned on the bond
interface
2. If a port leaves the bond and the port is the first port in the lag
group, then it is required to update all MAC entries to change the
destination port.

When the SW bridge was trying to add/remove entries to/from HW, the
access to HW was not protected by any lock. In this way, it was
possible to have race conditions.
Fix this by using the lan966x->mac_lock to protect parallel access to HW
for this cases.

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.
Update such that also the access to MAC entries in HW is protected by
this lock.

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.

At the moment, if devm_of_phy_get() returns an error the serdes
simply isn't set. While it is bad to ignore an error in general, there
is a particular bug that network isn't working if the serdes driver is
compiled as a module. In that case, devm_of_phy_get() returns
-EDEFER_PROBE and the error is silently ignored.
The serdes is optional, it is not there if the port is using RGMII, in
which case devm_of_phy_get() returns -ENODEV. Rearrange the error
handling so that -ENODEV will be handled but other error codes will
abort the probing.

The following two scenarios were failing for lan966x.
1. If the port had the address X and then trying to assign the same
address, then the HW was just removing this address because first it
tries to learn new address and then delete the old one. As they are
the same the HW remove it.
2. If the port eth0 was assigned the same address as one of the other
ports eth1 then when assigning back the address to eth0 then the HW
was deleting the address of eth1.
The case 1. is fixed by checking if the port has already the same
address while case 2. is fixed by checking if the address is used by any
other port.

Lan966x has 8 PTP programmable pins, where the last pins is hardcoded to
be used by PHC0, which does the frame timestamping. All the rest of the
PTP pins can be shared between the PHCs and can have different functions
like perout or extts. For now add support for PTP_FS_PEROUT.
The HW is not able to support absolute start time but can use the nsec
for phase adjustment when generating PPS.
