When per-packet rate reporting is enabled, the hardware can get stuck under
some conditions. It self-recovers quickly, but in practice this leads to
reduced performance.
In order to avoid running into this issue, disable per-packet rate reporting
by default and query the rx rate from firmware instead, unless monitor mode
is enabled.

In the MT7915 info, the fields for the WLAN index / queue overlap with the

There's an effort to move the remove() callback in the driver core to
not return an int, as nothing can be done if this function fails. To
make that effort easier, make the aux bus remove function void to start
with so that no users have to be changed sometime in the future.

Set max_busy_timeouts for variants known to support the TOPxx bits in
the SD_OPTION register. The timeout mechanism was running in the
background but not yet properly handled in the driver. So, let the MMC
core know when to not use R1B to avoid unhandled timeouts.
My datasheets for older variants (tmio_mmc.c) suggest that they support
it, too. However, actual bit descriptions are lacking, so I chose an
opt-in approach.

Currently we won't migrate irqs when offline CPUs, which has been
implemented on most architectures. That will lead to some devices work
incorrectly if the bound cores are offline.
While that can be easily supported by enabling GENERIC_IRQ_MIGRATION.
But i don't pretty known the reason it was not supported on all MIPS
platforms.

Linux doesn't own the memory immediately after the kernel image. On Octeon
bootloader places a shared structure right close after the kernel _end,
refer to "struct cvmx_bootinfo *octeon_bootinfo" in cavium-octeon/setup.c.
If check_kernel_sections_mem() rounds the PFNs up, first memblock_alloc()
inside early_init_dt_alloc_memory_arch() <= device_tree_init() returns
memory block overlapping with the above octeon_bootinfo structure, which
is being overwritten afterwards.
