Looking through my test logs, I find that the following build error has been
reported since  v6.1.166.

Building arm:ixp4xx_defconfig ... failed
--------------
Error log:
drivers/net/ethernet/xscale/ixp4xx_eth.c:390:39: warning: 'struct kernel_hwtstamp_config' declared inside parameter list will not be visible outside of this definition or declaration
   390 |                                struct kernel_hwtstamp_config *cfg,
       |                                       ^~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/xscale/ixp4xx_eth.c: In function 'ixp4xx_hwtstamp_set':
drivers/net/ethernet/xscale/ixp4xx_eth.c:408:16: error: invalid use of undefined type 'struct kernel_hwtstamp_config'

Backported patches in that driver are

5195b10c34b8 net: ethernet: xscale: Check for PTP support properly
a94d5447f6bf net: ixp4xx_eth: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()

where a94d5447f6bf introduces the problem and presumably was applied
to be able to apply 5195b10c34b8 without having to resolve conflicts.

Unfortunately, 'struct kernel_hwtstamp_config' is indeed not available in v6.1,
causing the build failure.

a94d5447f6bf can not be reverted on its own, so both patches would have to
be reverted to fix the problem.

The same problem is seen in v5.15.y since v5.15.202. The commits there are

144dde314698 net: ethernet: xscale: Check for PTP support properly
612c622ab8ef net: ixp4xx_eth: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()

I have copied the patch authors for advice.

Ugh not good, but no disaster, OpenWrt is the only downstream using stable
and it only used v6.12 and v6.18.

> I have copied the patch authors for advice.

I'd just pull them both out again. It's fixing a runtime crash that appear
only when you use ethtool. Annoying, but fringe system and not appearing
in normal use.

On ARCH_BRCMSTB using 32-bit and 64-bit ARM kernels, build tested on 
BMIPS_GENERIC:

The first time I booted this kernel I had an odd failure where it failed to mount most of the filesystems and the network came up incorrectly (different mac). Some sort of udev issue perhaps? Nothing useful in dmesg to report and I've been unable to reproduce the problem after several reboots. Just mentioning it in case anyone else has any weird issues with this one.
