NDA_NH_ID represents a remote ip or a group of remote ips.
It allows use of nexthop groups in lieu of a remote ip or a
list of remote ips supported by the fdb api.

Current code ignores the other remote ip attrs when NDA_NH_ID is
specified. In the spirit of strict checking, This commit adds a
check to explicitly return an error on incorrect usage.

The dynamic configuration interface for the General Params and the L2
Lookup Params tables was copy-pasted between E/T devices and P/Q/R/S
devices. Nonetheless, these interfaces are bitwise different.

The driver is using dynamic reconfiguration of the General Parameters
table for the port mirroring feature, which was therefore broken on
P/Q/R/S.

Note that this patch can't be backported easily very far to stable trees
(since it conflicts with some other development done since the
introduction of the driver). So the Fixes: tag is purely informational.

Newer compilers complain with W=1 builds that there are non-static
functions defined in sja1105_static_config.c that don't have a
prototype, because their prototype is defined in sja1105.h which this
translation unit does not include.

I don't entirely understand what is the point of these warnings, since
in principle there's nothing wrong with that. But let's move the
prototypes to a header file that _is_ included by
sja1105_static_config.c, since that will make these warnings go away.

Be there 2 switches spi/spi2.0 and spi/spi2.1 in a cross-chip setup,
both under the same VLAN-filtering bridge, both in the
SJA1105_VLAN_BEST_EFFORT state.

If we try to change the VLAN state of one of the switches (to
SJA1105_VLAN_FILTERING_FULL) we get the following error:

devlink dev param set spi/spi2.1 name best_effort_vlan_filtering value
false cmode runtime
[   38.325683] sja1105 spi2.1: Not allowed to overcommit frame memory.
               L2 memory partitions and VL memory partitions share the
               same space. The sum of all 16 memory partitions is not

               vl-forwarding-parameters-table.partspc.
[   38.356803] sja1105 spi2.1: Invalid config, cannot upload

This is because the spi/spi2.1 switch doesn't support tagging anymore in
the SJA1105_VLAN_FILTERING_FULL state, so it doesn't need to have any
retagging rules defined. Great, so it can use more frame memory
(retagging consumes extra memory).

But the built-in low-level static config checker from the sja1105 driver
says "not so fast, you've increased the frame memory to non-retagging
values, but you still kept the retagging rules in the static config".

So we need to rebuild the VLAN table immediately before re-uploading the
static config, operation which will take care, based on the new VLAN
state, of removing the retagging rules.

PHYs using the vsc8574_probe fail to be initialized and their

"could not attach PHY: -5".

This is because when the conversion of the MSCC PHY driver to use the
shared PHY package helpers was done, the base address retrieval and the
base PHY read and write helpers in the driver were modified. In
particular, the base address retrieval logic was moved from the
config_init to the probe. But the vsc8574_probe was forgotten. This
