We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory
at first, we now have a lot of consumer of it and we made it mandatory
so no need to have it under a cryptic name.

With addition of clkgen devices to the Armada38x we no longer
need to rely on get_tclk() to get the device frequency.
Leave it as a fallback, just in case.

The IFF_DRV_RUNNING flag is used to see if the interface needs
to be temporarily brought down during MTU change sequence.
The problem here is that this flag is cleared in mvneta_stop_locked,
resulting in the reinitialization logic never being executed after
MTU has been changed.
Fix that by saving the flag value before the interface is brought down.

Make neta use frequency obtained from clock, instead of
hardcoded one. Use default frequency in case of clock
device failure. Remove unnecessary function calls
to obtain frequency and use cached one instead.

mvneta_find_ethernet_prop_switch() is file-local static to
if_mvneta_fdt.c. Normally we would not need a function declararion
but in case MVNETA_DEBUG is set it becomes public. Move the
function declaration from if_mvneta.c to if_mvneta_fdt.c to avoid
a warning during each compile.
Fix device detach and attach routine. Add required Makefile
to build as a module. Remove entry from GENERIC, since now
it can be loaded automatically.

After MTU is updated we might start using allocating RX buffers from different pool. (MJUM9BYTES vs MCLBYTES)
Because of that we need to update the RX buffer size in hardware.
Previously it was done only when the interface was up, which is incorrect since MTU can be changed at any time.

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

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.
