From: Nikita Danilov <ndanilov@marvell.com>
We now implement .driver.pm callbacks, these
allows driver to work correctly in hibernate
usecases, especially when used in conjunction with
WOL feature.
Before that driver only reacted to legacy .suspend/.resume
callbacks, that was a limitation in some cases.

From: Nikita Danilov <ndanilov@marvell.com>
Device FW has a separate memory area where various
config fields are stored and could be used by the
driver.
Here we modify download/upload infrastructure to
allow accessing this area.
Lateron this will be used to configure various behaviours

Here we add a number of ethtool private flags
to allow enabling various loopbacks on HW.
Thats useful for verification and bringup works.

atlantic hardware does support UDP hardware segmentation offload.
This allows user to specify one large contiguous buffer with data
which then will be split automagically into multiple UDP packets
of specified size.
Bulk sending of large UDP streams lowers CPU usage and increases
bandwidth.
We did estimations both with udpgso_bench_tx test tool and with modified
iperf3 measurement tool (4 streams, multithread, 200b packet size)
over AQC<->AQC 10G link. Flow control is disabled to prevent RX side
impact on measurements.
No UDP GSO:
iperf3 -c 10.0.1.2 -u -b0 -l 200 -P4 --multithread
UDP GSO:
iperf3 -c 10.0.1.2 -u -b0 -l 12600 --udp-lso 200 -P4 --multithread
Mode CPU iperf speed Line speed Packets per second
-------------------------------------------------------------
NO UDP GSO 350% 3.07 Gbps 3.8 Gbps 1,919,419
SW UDP GSO 200% 5.55 Gbps 6.4 Gbps 3,286,144
HW UDP GSO 90% 6.80 Gbps 8.4 Gbps 4,273,117

aquantia.com domain. Thus, change the maintainers file and some other
references to @marvell.com domain
