4833f02a29 sfc: Move mdio_lock to struct falcon_nic_data
We only have direct access to MDIO on Falcon, so move this out of
struct efx_nic.

90d683afd1 sfc: Remove efx_rx_queue::add_lock
Ensure that efx_fast_push_rx_descriptors() must only run
from efx_process_channel() [NAPI], or when napi_disable()
has been executed.

Reimplement the slow fill by sending an event to the
channel, so that NAPI runs, and hanging the subsequent
fast fill off the event handler. Replace the sfc_refill
workqueue and delayed work items with a timer. We do
not need to stop this timer in efx_flush_all() because
it's safe to send the event always; receiving it will
be delayed until NAPI is restarted.

d730dc527a sfc: Allow DRV_GEN events to be used outside of selftests
Formerly, efx_test_eventq_irq() assumed it was the only user of
driver generated events. Allow it to interoperate with other users.

We can create more than 16 channels, so align event codes with
a multiple of 256 not 16.

e41c11ee0c sfc: Change falcon_probe_board() to fail for unsupported boards
The driver needs specific PHY and board support code for each SFC4000
board; there is no point trying to continue if it is missing.
Currently unsupported boards can trigger an 'oops'.
