Backport net: Allow class-e address assignment via ifconfig ioctl
While most distributions long ago switched to the iproute2 suite
of utilities, which allow class-e (240.0.0.0/4) address assignment,
distributions relying on busybox, toybox and other forms of
ifconfig cannot assign class-e addresses without this kernel patch.
While CIDR has been obsolete for 2 decades, and a survey of all the
open source code in the world shows the IN_whatever macros are also
obsolete... rather than obsolete CIDR from this ioctl entirely, this
patch merely enables class-e assignment, sanely.

I've sent this one upstream. This patch is critical if you want to run
with "prove lock correctness" (lockdep) and you happen to have certain
mtd devices. The misuse of the uninitialized object is undefined
behaviour, but being zeroed it does not appear to have actually broken
anything other than the lockdep engine.

Disable Marvell's hardware level MAC learning because it breaks station roaming.
When enabled it drops all frames that arrive from a MAC address
that is on a different port at learning table.
Problem description:
Multiple APs with inter-AP roaming connected to different ports,
when station moves from one AP on one port to another AP on another port,
traffic flow breaks down because the learning table is not updated.

In mainline kernel commit 02c7b25e5f5 ("netfilter: nf_tables: build-in
filter chain type") all chain filters were merged into one file and into
one kernel module to save some memory. The code protected by these
configuration options CONFIG_NF_TABLES_BRIDGE, CONFIG_NF_TABLES_IPV4,
CONFIG_NF_TABLES_ARP, CONFIG_NF_TABLES_IPV6, CONFIG_NF_TABLES_NETDEV and
CONFIG_NF_TABLES_INET was merged into the nft_chain_filter.c file which
is now always compiled into the nf_tables.ko file.
This only happened in kernel 4.19 and OpenWrt has to select these as
modules in older kennel versions. Mark them as build-in in the kernel
4.19 specific kernel configuration file which will then not be
overwritten by the package specific settings which try to make them
modular again.

In kernel commit 0168e8b361 ("netfilter: nat: merge ipv4/ipv6 masquerade
code into main nat module") the CONFIG_NF_NAT_MASQUERADE_IPV4 and
CONFIG_NF_NAT_MASQUERADE_IPV6 kernel configuration option were changed
to bool and the code will not be compiled as a own module any more, but
it will be integrated into nf_nat_ipv4.ko or nf_nat_ipv6.ko to save some
memory.
Activate these options as bool in the generic kernel 4.19 configuration
only, to always build them into the nf_nat_ipv*.ko modules. The kmod
file will still try to select them as module, but the generic
configuration will not be overwritten.

CONFIG_OF_NET depends on CONFIG_NVMEM in kernel 4.19. To fix some build

This makes the patches which were just copied in the previous commit
apply on top of kernel 4.19.
The patches in the backports-4.19 folder were checked if they are really
in kernel 4.19 based on the title and only removed if they were found in
the upstream kernel.
The following additional patches form the pending folder went into
upstream Linux 4.19:
pending-4.19/171-usb-dwc2-Fix-inefficient-copy-of-unaligned-buffers.patch
pending-4.19/190-2-5-e1000e-Fix-wrong-comment-related-to-link-detection.patch

pending-4.19/950-tty-serial-exar-generalize-rs485-setup.patch
pending-4.19/340-MIPS-mm-remove-mips_dma_mapping_error.patch
Bigger changes were introduced to the m25p80 spi nor driver, as far as I
saw it in the new code, it now has the functionality provided in this
patch:
pending-4.19/450-mtd-m25p80-allow-fallback-from-spi_flash_read-to-reg.patch
Part of this patch went upstream independent of OpenWrt:
hack-4.19/220-gc_sections.patch
This patch was reworked to match the changes done upstream.
The MIPS DMA API changed a lot, this patch was rewritten to match the
new DMA handling:
pending-4.19/341-MIPS-mm-remove-no-op-dma_map_ops-where-possible.patch
I did bigger manual changes to the following patches and I am not 100% sure if they are all correct:

The ledtrig-netdev was added to upstream Linux kernel 4.16, replace our
own version with the patch based on the upstream version.
This will remove the ledtrig-netdev support from kernel 3.18, because I
not want to spend time on backporting it to 3.18. This will make it
easier to use the upstream version with kernel 4.19, by just not
applying this patch.

This reverts commit 7e88753ace.
Using subpartitions (hierarchical layout) resulted in calling MTD ops of
parent partition instead of master device ops. That was expected and
should work but testing revealed some bugs.
Apparently the way MTD_ERASE_PARTIAL is implemented in the OpenWrt
breaks something and using parent partition ops triggers using that
code.
On SmartRG SR400ac it was resulting in:
[ 225.487519] jffs2: Erase at 0x01ac0000 failed immediately: errno -22
on the second boot (for some reason erasing was starting over) and it
was breaking flash access in a long term.

This helper uses hierarchical partitions layout following the way
upstream parsers work. It's closer to what we should use when mainlining
our solutions. It also doesn't require hacky casting of struct
mtd_partition to the const.
THIS WILL AFFECT KERNEL PRINTING PARTITIONS IN THE LOG
Something like:
[ 3.930158] 0x0000004e0000-0x000001fb0000 : "rootfs_data"
will get replaced by:
[ 3.907338] Creating 1 MTD partitions on "rootfs":
[ 3.912142] 0x00000031d400-0x000001ded400 : "rootfs_data"
It's important to understand that "rootfs_data" in above example is a
*subpartition* of the "rootfs" now. To get absolute addresses (e.g. for
some debugging purposes) one has to add them to the "rootfs", e.g.
[ 3.912548] 0x0000001c2c00-0x000001fb0000 : "rootfs"
(0x1c2c00 + 0x31d400 = 0x4e0000)

On the WNDAP620, the mdio and mdc lines are controlled by
the EMAC ethernet device. This results in a hen-vs-egg problem.
The rtl8367b driver is probed before the ethernet driver and
the mdio-bus is not available yet, which caused the rtl8367b
driver to fail.
This patch changes the rtl8366_smi_probe_of() function to
return -EPROBE_DEFER if the mdio-bus lookup failed and changes
rtl8366_smi_probe()'s signature to return the error code back to
the callee, so it can propagate back to the kernel. Which, will
retry the switch probe at a later time.

This allows us to use the bridge as a managed switch and gracefully
handle mixed tagged and untagged frames. Prior to this, the only
alternative was creating one bridge per vlan which quickly becomes a
nightmare and still won't let you mix both tagged and untagged frames on
the physical port without some complex ebtables magic.
This is in line with the notion that OpenWRT is the network go-to swiss
army knife when you need a nice set-and-forget, low maintenance box to
handle a specific task.
Current builds of the ip-bridge package already fully support this
feature so the only requirement is enabling the kernel config.
This is disabled by default so existing bridge configurations will not
be affected. This patch only gives the ability to turn it on with an
'ip link' command. If there is interest, I could look into making the
feature accessible via uci configuration.
It causes about 3.1% hit on raw bridging speed, which is relatively
trivial considering that I had to use 300 byte packets to strain the CPU
enough to notice a slowdown at all. The ER8 would chug along at wire
speed otherwise, and that's using only one core. Since the typical
bridge use case on OpenWRT is wireless, I doubt it would be noticeable
at all.

In terms of kernel size, it uses 16KB (6753K vs 6737K on ER8) so a
