d881f65da1 realtek: eth: Do not write directly to dev->addr
One is never to write to dev->addr directly. In 6.1 it will be a const and
with the newly enabled WERROR, we get a failing grade.

Lets fix this ahead of time.

a872570c04 realtek: remove redundant is_lagmember checks
All callers of the rtl83xx_mc_group_* functions already do the same
check, so these aren't needed.

For rtl83xx_mc_group_alloc, this branch also incorrectly returned 0
instead of a negative value. If the branch wasn't effectively dead code
anyway, this could potentially have caused bugs, as 0 is a valid
multicast group entry index.

98a3b52380 realtek: remove store_mcgroups/load_mcgroups
The current implementation only works when store and load are called for
the same port without any other calls in between. This is because the
store function only saves a single port number instead of a portmask for
each group. It also doesn't take into account that the allocation of
multicast group entries might change between store/load calls.

As a result, the multicast port mask table gets corrupted. This also
includes the reserved entry for unknown multicast, which gets corrupted
even when no other mdb entries have been added.

Remove the code for storing/loading multicast groups entirely, as the
original commit message doesn't offer a convincing reason why this would
be necessary in the first place.

6772ae1172 realtek: don't add CPU port to multicast portmasks
There shouldn't be any reason to forward all multicast to the CPU. The
original commit message also doesn't provide a reason for this seemingly
unrelated change.

The current implementation of the delete method is also broken, as it
entirely removes any entry when the portmask contains only the CPU port,
even if it was explicitly created.

57df840670 realtek: don't treat first multicast portmask entry as reserved
There doesn't appear to be a reason to do this, as only the last entry
is actually reserved for unknown multicast.

This also fixes two issues:
 - As the increment happened after the bounds check, the value of the
   actually reserved last entry could be overwritten.
 - On deletion of entries, a corresponding decrement was missing,
   causing the wrong entry to be marked as free.

5d34fc92ec realtek: fix standalone ports in presence of static fdb entries
The registers L2_PORT_STATIC_MV_ACT seem to specify the action to take
when the source address of a packet exists as a static fdb entry on
another port. By default the configured action is to drop such packets.

For standalone ports, this behaviour is undesired, as all traffic should
be forwarded to the CPU. So change the action to forward on standalone
ports.

A situation where this issue can occur is when a non-offloaded bond
interface is part of a bridge. In that case, the CPU port will have fdb
entries for devices connected to the bond interface, which are managed
by the assisted learning feature.

For now, this is only implemented for RTL838x/RTL839x, as the available
set of registers differs for the other devices.

registers directly.

de2dc3feae realtek: return correct error value for phy ops
A behavioural change was introduced with commit 758c88b969 ("realtek:
Whitespace and codestyle cleanup") causing rtl838x_read_phy() and
rtl838x_write_phy() to unconditionally return -ETIMEDOUT. As a result,
probing the device during boot fails:

    Error setting up netdev, freeing it again.
    rtl838x-eth: probe of 1b00a300.ethernet failed with error -5

Fix the bootloop caused by this regression with kernel 5.15 on rtl838x
devices, by properly returning 0 on success.

Tested on a Netgear GS108T v3, a Netgear GS310TP v1, a Zyxel GS1900-8HP

ae0a3f88ac realtek: restructure rtl_table_read/write
These two functions are identical apart from writing different values to
the read/write bit. Create a new function rtl_table_exec to reduce code
duplication.

Also replace the unbounded busy-waiting loop. The new implementation may
sleep, but as the hardware typically responds before the first poll, any
callers doing many table accesses still need to make sure not to block
other kernel tasks themselves.

So far, polling timeout errors are only handled by logging an error, but
a return value is added to allow proper handling in the future.

c94ca63ed4 realtek: don't set L2LEARNING flag in rtl83xx TX header
As learning for the CPU port is now disabled globally, the bit in the
TX header doesn't have any effect anymore. Remove it to make the header
consistent with the global configuration.

Originally, this change was intended to be applied before commit
eb456aedfe ("realtek: use assisted learning on CPU port"), which is
why the commit message incorrectly mentions that the TX header already
disables learning.

The reason for disabling learning on the CPU port in the first place is
that it doesn't work correctly when packets are trapped to the CPU and
then forwarded by the CPU to other ports. In that case, the switch would
incorrectly learn the CPU port as source. An example that triggered this
issue are Multicast Listener Reports and IGMP membership reports.
