This series correct some misuse of NAPI APIs in the driver.

ibmvnic: remove duplicate napi_schedule call in open function
drivers/net/ethernet/ibm/ibmvnic.c | 14 ++-
__ibmvnic_open calls napi_disable without checking whether NAPI polling
has already been disabled or not. This could cause napi_disable
being called twice, which could generate deadlock. For example,
the first napi_disable will spin until NAPI_STATE_SCHED is cleared
by napi_complete_done, then set
During adapter reset, do_reset/do_hard_reset calls ibmvnic_open(),
which will calls napi_schedule if previous state is VNIC_CLOSED
(i.e, the reset case, and "ifconfig down" case). So there is no need
for do_reset to call napi_schedule again at the end of the function
though napi_schedule will negle
Remove the unnecessary napi_schedule() call in __ibmvnic_open() since
interrupt_rx() calls napi_schedule_prep/__napi_schedule during every
receive interrupt.

Some Ethernet switches might only be able to support disabling multicast

Normally, the bootloader will already initialize the MAC address
registers of the ENETC and the driver will just use them or generate a
random one, if it is not initialized.
Add a new way to provide the MAC address: via device tree. Besides the
usual 'mac-address' property, there is also the possi
