Vladimir Oltean ca0b272b48 net: mscc: ocelot: install MAC addresses in .ndo_set_rx_mode from process context ... Currently ocelot_set_rx_mode calls ocelot_mact_learn directly, which has a very nice ocelot_mact_wait_for_completion at the end. Introduced in commit 639c1b2625 ("net: mscc: ocelot: Register poll timeout should be wall time not attempts"), this function uses readx_poll_timeout which triggers a lot of lockdep warnings and is also dangerous to use from atomic context, potentially leading to lockups and panics. Steen Hegelund added a poll timeout of 100 ms for checking the MAC table, a duration which is clearly absurd to poll in atomic context. So we need to defer the MAC table access to process context, which we do via a dynamically allocated workqueue which contains all there is to know about the MAC table operation it has to do.
