starting from upstream commit 577b4eb23811 ("ubi: Reject MLC NAND")
it is not allowed to use UBI and UBIFS on a MLC flavoured NAND flash chip. [1]
According to David Oberhollenzer [2]:
The real problem is that on MLC NAND, pages come in pairs.
Multiple voltage levels inside a single, physical memory cell are used to
encode more than one bit. Instead of just having pages that are twice as big,
the flash exposes them as two different pages. Those pages are usually not
ordered sequentially either, but according to a vendor/device specific
pairing scheme.
Within OpenWrt, devices utilizing this type of flash,
combined with UBI(fs) will be bricked when a user upgrades
from 17.01.4 to a newer version as the MLC will be refused.
As these devices are currently advertised as supported by OpenWrt,
we should at least maintain the original state during the lifecycle
of the current releases.
Support can be gracefully ended when a new release-branch is created.

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

The previous round of fixes for the 82574 chip cause an issue with
emulated e1000e devices in VMware ESXi 6.5. It also contains changes
that are not strictly necessary. These patches fix the issues introduced
in the previous series, revert the unnecessary changes to avoid
unforeseen fallout, and avoid a case where interrupts can be missed.
The final two patches of this series are already in the kernel, so no

This is a new & warm feature that allows nesting partiitons in DT and
mixing their types (e.g. static vs. dynamic). It's very useful for
boards that have most partitions static but some of them require extra
parsing (e.g. a "firmware" partition).
It's required to successfully backport support for new devices using
that new syntax in their DT files.
Since brcm63xx has a custom alternative patch the upstream one is being
reverted for it. The plan is to make brcm63xx use the upstream
implementation.

The 666-Add-support-for-MAP-E-FMRs-mesh-mode.patch kernel patches
break the possibility for using an ip4ip6 tunnel interface as a fall
back interface accepting ip4-in-ip6 tunneled packets from any remote
address. This works out of the box with any normal (non-666-patched)
kernel and can be configured by setting up an 'ip -6 tunnel' with type
'any' or 'ip4ip6' and a remote address of '::'.
The misbehavior comes with line 290 the patch which discards all packets
that do not show the expected saddr, even if no single fmr rule was
defined and despite the validity of the saddr was already approved earlier.

Backport hot off the press upstream netlink patch. Fixes stats display
from CAKE qdisc on MIPS allowing us to bump CAKE to latest version.
The gen_stats facility will add a header for the toplevel nlattr of type
TCA_STATS2 that contains all stats added by qdisc callbacks. A reference
to this header is stored in the gnet_dump struct, and when all the
per-qdisc callbacks have finished adding their stats, the length of the
containing header will be adjusted to the right value.
However, on architectures that need padding (i.e., that don't set
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added
before the stats, which means that the stored pointer will point to the
padding, and so when the header is fixed up, the result is just a very
big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS
struct, this problem has been mostly invisible, but we exposed it with
the netlink attribute-based statistics in CAKE.
Fix the issue by fixing up the stored pointer if it points to a padding
nlattr.

This is important fix for flash parsing in some corner cases. In case
of TRX subpartition with rootfs being aligned to the flash block size it

standalone partition was resulting in an incorrect "firmware" partition
size and possibly broken sysupgrade.
It wasn't noticed before because "rootfs" alignment depends on a kernel
size. It can happen though - depending on the configuration and the
