Setting the plmn to '0' (auto) will implicitly lead to a (delayed)
network re-registration, which could further lead to some timing
related issues in the qmi proto handler.
On the other hand, if you switch back from manual plmn selection
to auto mode you have to set it to '0', because this setting is
permanently "saved" in the wwan module.
Conclusion:
If plmn is configured, check if it's already set euqally in the module.
If so, do nothing. Otherwise set it.

TP-Link has developed a number of access points based on the AP152
reference board. In the EAP-series of 802.11ac access points, this
includes the following devices with one ethernet port:
* EAP225 v1/v2
* EAP225 v3
* EAP225-Outdoor v1
* EAP245 v1
Since the only differences between these devices are the ath10k wireless
radios and LEDs, a common base is provided for the overlapping support
requirements.
Hardware commonalities:
* SoC: QCA9563-AL3A MIPS 74kc v5.0 @ 775MHz, AHB @ 258MHz
* RAM: 128MiB DDR2 @ 650MHz
* Flash: 16MiB SPI NOR

* Wi-Fi 5Ghz: ath10k chip on PCIe

Currently sfp_select_interface() return the fastest interface that
the sfp modules supports even if the phy don't support that mode.
For example an GPON module that support both 2500basex and 1000basex.
Currently sfp_select_interface() picks 2500basex instead of 1000basex.
So limit the interfaces which both sides supports before calling
sfp_select_interface() or return an error if we don't have match.

Some devices (especially QCA ones) are already using hardcoded partition
names with colons in it. The OpenMesh A62 for example provides following
mtd relevant information via cmdline:
root=31:11 mtdparts=spi0.0:256k(0:SBL1),128k(0:MIBIB),384k(0:QSEE),64k(0:CDT),64k(0:DDRPARAMS),64k(0:APPSBLENV),512k(0:APPSBL),64k(0:ART),64k(custom),64k(0:KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive) rootfsname=rootfs rootwait
The change to split only on the last colon between mtd-id and partitions
will cause newpart to see following string for the first partition:
KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive)
Such a partition list cannot be parsed and thus the device fails to boot.
Avoid this behavior by making sure that the start of the first part-name
("(") will also be the last byte the mtd-id split algorithm is using for
its colon search.

The wcsnrtombs function in all musl libc versions up through 1.2.1 has
been found to have multiple bugs in handling of destination buffer
size when limiting the input character count, which can lead to
infinite loop with no forward progress (no overflow) or writing past
the end of the destination buffera.
This function is not used internally in musl and is not widely used,
but does appear in some applications. The non-input-limiting form
wcsrtombs is not affected.
All users of musl 1.2.1 and prior versions should apply the attached
patch, which replaces the overly complex and erroneous implementation.
The upcoming 1.2.2 release will adopt this new implementation.

using the filename instead of the url-filename in case the previous
download attempt using the url-filename failed.
This is required, as the OpenWrt sources mirrors serve files using the
filename files might be renamed to after downloading. If the original
mirror for a file where url-filename and filename do not match goes
down, the download failed prior to this patch.
Further improvement can be done by performing this only for the

The ImageBuilder downloads pre-built packages and adds them to images.
This process uses `opkg` which has the capability to verify package list
signatures via `usign`, as enabled per default on running OpenWrt
devices.
Until now this was disabled for ImageBuilders because neither the `opkg`
keys nor the `opkg-add` script was present during first packagelist
update.
To harden the ImageBuilder against *drive-by-download-attacks* both keys
and verification script are added to the ImageBuilder allowing `opkg` to
verify downloaded package indices.
This commit adds `opkg-add` to the ImageBuilder scripts folder. The keys
folder is added to ImageBuilder $TOPDIR to have an obvious place for users to
store their own keys. The `option check_signature` is appended to the
repositories.conf file. All of the above only happens if the Buildbot
runs with the SIGNATURE_CHECK option.
The keys stored in the ImageBuilder keys/ are the same as included in
the openwrt-keyring package. To avoid the chicken-egg problem of
downloading and verifying a package, containing signing keys, the keys
are added during the ImageBuilder generation. They are same as in
shipped images (stored at `/etc/opkg/keys/`).
To allow a local package feed in which the user can add additional
packages, a local set of `usign` and `ucert` keys is generated, same as
building OpenWrt from source. The private key signs the local repository
inside the packages/ folder. The local public key is added to the keys/
folder to be considered by `opkg` when updating repositories. This way a
local package feed can be modified while requiring `opkg` to check
signatures for remote feed, making HTTPS optional.
The new option `ADD_LOCAL_KEY` allows to add the local key inside the
created images, adding the advantage that sysupgrades can validate the
ImageBuilders local key.

Commit 5d76065 moved the creation of the symvers directory to
include/kernel-build.mk. This is fine when building from scratch. But
when unpacking an SDK the directory doesn't exist and because the kernel
won't be built (again) this directory will not be created by the build
system, causing build failure if make tries to copy files into it.
This moves the creation of the symvers directory back into
include/kernel.mk so that the directory is created in any case.
