These patch sets are quite invasive for a stable kernel. It looks like
the default behavior is untouched if cq_cpumask is zero. However, I
would like to see some discussion with upstream as to the efficacy of
IRQ affinity with this device.
Mykyta - can you develop and send a patch for current upstream review ?
