Hi,
I am testing Mesh modes uing two different hardware Mesh nodes, first node was
configured in an 20 MHz mode (driver:ath9k backported from 4.4.2-1) and second node is
configured in ac 20MHz mode (driver: ath10K backported from ath10k git).
Firmware version : firmware-5.bin_10.2.4.70.63-2
I observed firmware crash whenever there are mismatch between HT/VHT capabilities.
Following crash errors are flashed.
Please help me on this.Can Mesh nodes connect with different capabilities? What is wrong
with firmware.
