Merge branch 'aquantia-next'

Igor Russkikh says:

====================
Aquantia Marvell atlantic driver updates 11-2019

Here is a bunch of atlantic driver new features and updates.

Shortlist:
- Me adding ethtool private flags for various loopback test modes,
- Nikita is doing some work here on power management, implementing new PM API,
  He also did some checkpatch style cleanup of older driver parts.
- I'm also adding a new UDP GSO offload support and flags for loopback activation
- We are now Marvell, so I am changing email addresses on maintainers list.

v2: styling, ip6 correct handling in udpgso
====================

+ UDP GSO hardware offload
+ ---------------------------------
+ UDP GSO allows to boost UDP tx rates by offloading UDP headers allocation
+ into hardware. A special userspace socket option is required for this,
+ could be validated with /kernel/tools/testing/selftests/net/
+
+    udpgso_bench_tx -u -4 -D 10.0.1.1 -s 6300 -S 100
+
+ Will cause sending out of 100 byte sized UDP packets formed from single
+ 6300 bytes user buffer.
+
+ UDP GSO is configured by:
+
+    ethtool -K eth0 tx-udp-segmentation on
+
+ Private flags (testing)
+ ---------------------------------
+
+ Atlantic driver supports private flags for hardware custom features:
+
+	$ ethtool --show-priv-flags ethX
+
+	Private flags for ethX:
+	DMASystemLoopback  : off
+	PKTSystemLoopback  : off
+	DMANetworkLoopback : off
+	PHYInternalLoopback: off
+	PHYExternalLoopback: off
+
+ Example:
+
+	$ ethtool --set-priv-flags ethX DMASystemLoopback on
+
+ DMASystemLoopback:   DMA Host loopback.
+ PKTSystemLoopback:   Packet buffer host loopback.
+ DMANetworkLoopback:  Network side loopback on DMA block.
+ PHYInternalLoopback: Internal loopback on Phy.
+ PHYExternalLoopback: External loopback on Phy (with loopback ethernet cable).
