434502930f net: dsa: Mop up remaining NET_DSA_HWMON references
Previous patches have moved the temperature sensor code into the
Marvell PHYs. A few now dead references to NET_DSA_HWMON were left
behind. Go reap them.

9d490b4ee4 net: dsa: rename switch operations structure
Now that the dsa_switch_driver structure contains only function pointers
as it is supposed to, rename it to the more appropriate dsa_switch_ops,
uniformly to any other operations structure in the kernel.

No functional changes here, basically just the result of something like:
s/dsa_switch_driver *drv/dsa_switch_ops *ops/g

However keep the {un,}register_switch_driver functions and their
dsa_switch_drivers list as is, since they represent the -- likely to be
deprecated soon -- legacy DSA registration framework.

In the meantime, also fix the following checks from checkpatch.pl to
make it happy with this patch:

    CHECK: Comparison to NULL could be written "!ops"
    #403: FILE: net/dsa/dsa.c:470:
    +	if (ops == NULL) {

    CHECK: Comparison to NULL could be written "ds->ops->get_strings"
    #773: FILE: net/dsa/slave.c:697:
    +		if (ds->ops->get_strings != NULL)

    CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats"
    #824: FILE: net/dsa/slave.c:785:
    +	if (ds->ops->get_ethtool_stats != NULL)

    CHECK: Comparison to NULL could be written "ds->ops->get_sset_count"
    #835: FILE: net/dsa/slave.c:798:
    +		if (ds->ops->get_sset_count != NULL)

    total: 0 errors, 0 warnings, 4 checks, 784 lines checked

43c44a9f65 net: dsa: make the STP state function return void
The DSA layer doesn't care about the return code of the port_stp_update
routine, so make it void in the layer and the DSA drivers.

Replace the useless dsa_slave_stp_update function with a
dsa_slave_stp_state function used to reply to the switchdev
SWITCHDEV_ATTR_ID_PORT_STP_STATE attribute.

In the meantime, rename port_stp_update to port_stp_state_set to
explicit the state change.

477b184526 net: dsa: drop vlan_getnext
The VLAN GetNext operation is specific to some switches, and thus can be
complicated to implement for some drivers.

Remove the support for the vlan_getnext/port_pvid_get approach in favor
of the generic and simpler port_vlan_dump function.

65aebfc002 net: dsa: add port_vlan_dump routine
Similar to port_fdb_dump, add a port_vlan_dump function to DSA drivers
which gets passed the switchdev VLAN object and callback.

This function, if implemented, takes precedence over the soon legacy
vlan_getnext/port_pvid_get approach.

a6692754d6 net: dsa: pass bridge down to drivers
Some DSA drivers may or may not support multiple software bridges on top
of an hardware switch.

It is more convenient for them to access the bridge's net_device for
finer configuration.

Removing the need to craft and access a bitmask also simplifies the
code.

This patch changes the signature of bridge related functions, update DSA
drivers, and removes dsa_slave_br_port_mask.
