Most wireless routers and access points can operate in multiple bands
simultaneously. Vendors often equip their devices with per-band LEDs.
Add defines for those very common functions to allow cleaner & clearer
bindings.

I made a second attempt on debugging some longstanding stability issues

with a pretty slow arch timer running at 36,8 kHz.
After 0 to 20 minutes of close to zero activity I experience hangs and I

Years ago I added support for Broadcom's BCM53573 SoCs. We released
firmwares based on Linux 4.4 (and later on 4.14) that worked almost

Hi Josh,
I'm OpenWrt developer and those CLM BLOBs have significant meaning for
this project. They allow OpenWrt users to use their devices with full

For that let me speak up regarding this PATCH case.

Netfilter allows disabling checksum verification of incoming packets by
setting nf_conntrack_checksum variable. That feature is very useful for
home routers which:
1. Most of the time just /forward/ network traffic
2. Have slow CPU(s) and csum calculation is a challenge

Hi Rafal,
Maybe we could disable frames buffering by default until it is fixed?
Also, maybe we could do more tests on newer models such as mt7986/81 to
make this patch benefit more models?
