layerscape: reverse changes to ndo_get_stats64
The NXP LSDK kernel backported changes for interface ndo_get_stats64 functions from mainline, this causes a compile error with backports/mac80211, which expects the original 4.9 defintion. As reversing the ndo_get_stats64 change signifcantly reduces the size of patch 601, the patches that were aggregated into it have been disaggregated.

+Subject: [PATCH] net: centralize net_device min/max MTU checking
+
+While looking into an MTU issue with sfc, I started noticing that almost
+every NIC driver with an ndo_change_mtu function implemented almost
+exactly the same range checks, and in many cases, that was the only
+practical thing their ndo_change_mtu function was doing. Quite a few
+drivers have either 68, 64, 60 or 46 as their minimum MTU value checked,
+and then various sizes from 1500 to 65535 for their maximum MTU value. We
+can remove a whole lot of redundant code here if we simple store min_mtu
+and max_mtu in net_device, and check against those in net/core/dev.c's
+dev_set_mtu().
+
+In theory, there should be zero functional change with this patch, it just
+puts the infrastructure in place. Subsequent patches will attempt to start
+using said infrastructure, with theoretically zero change in
+functionality.

+ timeouts
+
+[core-linux part]
+
+Update txq0's trans_start in order to prevent the netdev watchdog from
+triggering too quickly. Since we set the LLTX flag, the stack won't update
+the jiffies for other tx queues. Prevent the watchdog from checking the
+other tx queues by adding the NETIF_HW_ACCEL_MQ flag.

+Subject: [PATCH] base: soc: Introduce soc_device_match() interface
+
+We keep running into cases where device drivers want to know the exact
+version of the a SoC they are currently running on. In the past, this has
+usually been done through a vendor specific API that can be called by a
+driver, or by directly accessing some kind of version register that is
+not part of the device itself but that belongs to a global register area
+of the chip.
+
+Common reasons for doing this include:
+
+- A machine is not using devicetree or similar for passing data about
+ on-chip devices, but just announces their presence using boot-time
+ platform devices, and the machine code itself does not care about the
+ revision.
+
+- There is existing firmware or boot loaders with existing DT binaries
+ with generic compatible strings that do not identify the particular
+ revision of each device, but the driver knows which SoC revisions
+ include which part.
+
+- A prerelease version of a chip has some quirks and we are using the same
+ version of the bootloader and the DT blob on both the prerelease and the
+ final version. An update of the DT binding seems inappropriate because
+ that would involve maintaining multiple copies of the dts and/or
+ bootloader.
+
+This patch introduces the soc_device_match() interface that is meant to
+work like of_match_node() but instead of identifying the version of a
+device, it identifies the SoC itself using a vendor-agnostic interface.
+
+Unlike of_match_node(), we do not do an exact string compare but instead
+use glob_match() to allow wildcards in strings.
