This patch set addresses some of the feedback received on the dpaa2-ethsw
driver: https://lore.kernel.org/patchwork/patch/1113335/.

There are no functional changes but rather just code cleanup.

[PATCH 01/10] staging: fsl-dpaa2/ethsw: remove IGMP default address

[Ioana Ciornei]

Do not add an IGMP multicast address by default since we do not support
Rx/Tx ar the moment.

[PATCH 02/10] staging: fsl-dpaa2/ethsw: enable switch ports only on dev_open

[Ioana Ciornei]

At probe time, only the DPSW object should be enabled without the
associated ports, which will get enabled on dev_open. Remove the
ethsw_open() and ethsw_stop() functions and replace them only with
dpsw_enable()/_disable().

[PATCH 04/10] staging: fsl-dpaa2/ethsw: remove debug message

Since ethtool will be loud enough if the .set_link_ksettings() callback
fails, remove the debug messages which do not add additional
information.
