No luck for now. 160Mbps seems to be the limit using the mentioned 
configuration (I had to fix the channel to 36 and add 
vht_oper_centr_freq_seg0_idx=42 again to bring up the AP)
I'm using sparkLAN WPEA-351AC cards with QCA9880 chip set.
I' ve got this info from SparkLAN:

You are probably using Compex cards with the same chip set?
Based on the chip set, I should be able to get higher bitrates or is it 
possbile that the WPEA-351AC card needs another configuration?

Thanks a lot,
