I'm having another attempt at trying to getting the 'store dscp into
conntrack connmark' functionality into upstream kernel, since the
restore function (act_ctinfo) has been accepted.
The syntax has changed from 'savedscp' to 'set-dscpmark' since that
conforms more closely with existing functionality.
4.14 backport is more of a hack since the structure versioning
mechanism isn't in place.

- Remove the "RGMII TX delay fixup" hack and the associated
DT-property. It was never used in a DT-based platform and
solved a problem which can be mitigated by using correct
delays on the MAC side.
- Remove the patch to enable platform-data support for the
at803x driver. It was only used by ar71xx which does not
(and never will) support kernel 4.19 or later.
- Remove the SmartEEE DT-configuration patch. As explained
previously, this patch never disabled the Atheros SmartEEE
implementation, but rather "standard" EEE. This can be done
on device-tree compatible platforms by adding the
"eee-broken-1000t" or "eee-broken-100tx" properties to the PHY
node. As all usages of the old properties are migrated, this
patch can be removed.

Currently it's not possible to effectively mark a "firmware" partition
as read-only. The sub-partitions "kernel", "rootfs" and "rootfs_data"
are always created as read-write (ignoring the parent access mode).
This patch enforces the access mode of sub-partitions to match the
parent partition, which is useful for recovery images that are meant
to be fully read-only to avoid accidental damage from end-user.
An example of such implementation (read-only firmware image) is the
recovery image used on the Zsun-SD100 [1].
Please note the related patch for fstools [2] to enable this read-only
concept.

The SPI-NAND framework from Linux uses common driver code that is then
"tuned" by a tiny struct of chip-specific data that describes
available commands, timing, and layout (data and OOB data). Several
manufacturers and chips have been added since 4.19, several of which
are used in devices already supported by OpenWrt (typically with no or
"legacy" access to their NAND memory). This commit catches up the
supported-chip definitions through Linux 5.2-rc6 and linux/next.
The driver is only compiled for platforms with CONFIG_MTD_SPI_NAND=y.

This fixes off-by-one error introduced in commit dc76900021
("kernel: Correctly search for the FIT image in mtd partition.")
Function `mtd_read` starts reading at `offset` and
needs `hdr_len` number of bytes to be available. Suppose
the easiest case when `offset` is `0` and `hdr_len` equals
to `mtd->size` - the `for` loop will not be entered even
when enough bytes are available to be read.
Same happens for any non-zero `offset`, when `hdr_len` is
just enough bytes to be read until `mtd->size` is reached.
Imagine that for example `mtd->size=5`, `offset=4` and
`hdr_len=1`. Then `offset+hdr_len=5` and the check has to
be `offset+hdr_len <= mtd->size`, i.e. `5 <= 5`. The
check for `offset + hdr_len` value needs to be inclusive,
therefore use `<=`.

Luckily this parser is needed by Fon FON2601 only which uses DT-based

"fonfxc,uimage" string.
That said triggering this parser based on the "firmware" (or whatever
MTD_SPLIT_FIRMWARE_NAME is) partiiton name is not needed. It can be
dropped which will automatically fix the Buffalo WZR-HP-G300NH case.

1) It was /requested/ from DT using "fonfxc,uimage" compatible string
2) It was called by parsing code after finding "firmware"

Code added in the /fix/ commit basically just disabled the second case.
If that's the real goal it could be achieved by simply dropping type
MTD_PARSER_TYPE_FIRMWARE. It may however require another solution as
it's possible that some non-DT target actually needs fonfxc uImage

Signed-off-by: Petr Štetiar <ynezz@true.cz>
savedscp is a method of storing the DSCP of an ip packet into conntrack
mark. In combination with a suitable tc filter action (conndscp but may
end up being integrated into connmark) DSCP values are able to be stored
on egress and restored on ingress across links that otherwise alter or
bleach DSCP.
This is useful for qdiscs such as CAKE which are able to shape according
to policies based on DSCP.
Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway.
The ingress problem is solved by the tc filter, but the tc people didn't
like the idea of tc setting conntrack mark values, though they are ok
with reading conntrack values and hence restoring DSCP from conntrack
marks.
x_tables CONNMARK with the new savedscp action solves the problem of
storing the DSCP to the conntrack mark.
It accepts 2 parameters. The mark is a 32bit value with usually one 1
bit set. This bit is set when savedscp saves the DSCP to the mark.
This is useful to implement a 'one shot'
iptables based classification where the 'complicated' iptables rules are
only run once to classify the connection on initial (egress) packet and
subsequent packets are all marked/restored with the same DSCP. A mark
of zero disables the setting of a status bit/s.
The mask is a 32bit value of at least 6 contiguous bits and represents
the area where the DSCP will be stored.
e.g.
iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --savedscp-mark 0xfc000000/0x01000000
Would store the DSCP in the top 6 bits of the 32bit mark field, and use
the LSB of the top byte as the 'DSCP has been stored' marker.

Commit fcb41decf6 ("config: enable some useful features on

When the flow offloading framework intends to delete a flow from the
hardware table, it is necessary to retrieve the namespace from
nf_flowtable->ft_net. However, no one ever wrote the namespace into
nf_flowtable->ft_net in advance. So the framework will mistakenly use a
NULL namespace to execute dev_get_by_index_rcu(net, ifindex), leading to
