John Thomson 69d0ff5803 ipq40xx: ipqess: pass up ethdev_addr probe defer
Notify via dev_info when a random MAC address is set.
of_get_ethdev_address can return -EPROBE_DEFER for NVMEM devices,
return this up, so that ipqess can defer as well.
Also move this MAC assignment from _init into _probe, so that this defer
can happen earlier.

Before change, with MAC address allocated from a built-in NVMEM layout
driver (mikrotik,routerboot-nvmem) with extra of_get_ethdev_address
result and random MAC printfs:
[    1.197571] ipqess-edma c080000.ethernet: ipqess_init of_get_ethdev_address ret:-517, of_node: /soc/ethernet@c080000

[    5.055929] ipqess-edma c080000.ethernet eth0: configuring for fixed/internal link mode

after change:

with extra __func__ printf to show _probe and _init:

[    1.173784] ipqess-edma c080000.ethernet: of_get_ethdev_address: -517

Subject: [PATCH] net: qualcomm: ipqess: enable threaded NAPI by default
Threaded NAPI provides a nice performance boost, so lets enable it by
default.
We do however need to move the __napi_schedule() after HW IRQ has been
cleared in order to avoid concurency issues.
