[PATCH RFC v2 net-next 0/4] mv88e6xxx: setting 2500base-x mode for CPU/DSA port in dts

["Marek Behún" <marek.behun@nic.cz>]

Hi,

here is another proposal for supporting setting 2500base-x mode for
CPU/DSA ports in device tree correctly.

The changes from v1 are that instead of adding .port_setup() and
.port_teardown() methods to the DSA operations struct we instead, for
CPU/DSA ports, call dsa_port_enable() from dsa_port_setup(), but only
after the port is registered (and required phylink/devlink structures
exist).

The .port_enable/.port_disable methods are now only meant to be used
for user ports, when the slave interface is brought up/down. This
proposal changes that in such a way that these methods are also called
for CPU/DSA ports, but only just after the switch is set up (and just
before the switch is tore down).

If we went this way, we would have to patch the other DSA drivers to
check if user port is being given in their respective .port_enable
and .port_disable implmentations.

What do you think about this?

Marek
