It appears we must read MIB values as 2 4-byte words, lower address
first. A single 8-byte MIB read returns the value with the lower 4
bytes copied into the upper 4 bytes, resulting in bogus byte counter
values.

The mvneta device requires MVNETA_TX_CMD_L4_CHECKSUM_NONE bit to be set in the tx descriptor is checksum not required. However, mvneta_tx_set_csumflag() is not setting this flag currently, causing the hardware to randomly corrupt IP header during transmission.
This affects injected IPv4 packets that skips kernel IP stack processing (e.g. DHCP), as well as all IPv6 packets, since the driver currently does not offload csum for IPv6.
The fix is to remove all the early return paths from mvneta_tx_set_csumflag() which do not set the MVNETA_TX_CMD_L4_CHECKSUM_NONE flag.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

This patch introduces processing of the frames
up to 9kB by the mvneta driver. Some versions of
this NIC limit TX checksum offloading, depending
on the frame size, so add appropriate handling
of this feature.

In the latest Linux kernel revisions the DSA (Distributed
Switch Architecture) device tree binding was changed.
Instead of the top level dsa@ node, the switch and its
ports is represented as a child node of the mdio bus.
With that other modifications were added, such as
relation with the ethernet port of the SoC. Adjust
e6000sw etherswitch and mvneta drivers to that.
Tested on Armada 3720 EspressoBin and Armada 388 Clearfog Pro boards.

OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.
For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.

Defining a variable with the description and then only use it in the
SYSCTL declaration led to an unused variable warning. In the SYSCTL the
passed value is discarded using __DESCR.
This patch enables using NETA driver on Marvell Armada 3700 SoC
by introducing new compatible string, modifying clock source
obtaining and also excluding unnecessary parts.
The driver is added as a build option for arm64 platforms as well.

Now the virtual address of received buffer is taken from a software ring.
Thanks to this, we can use the NETA driver on 64 bits architecture and
avoid 32-bit buf_cookie descriptor field limitation.

This patch contains a new driver for the network unit of Marvell
Armada 38x/XP SoCs, called NETA. This support was thoroughly tested
and optimised in terms of stability and performance. Additional
hardware features, like Buffer Management (BM) or Parser and Classifier
(PnC) will be progressively supported as needed.
