Is setting tx/rx chainmask to 0x0 make any sense at all? Shouldn't we deny it or make it fallback to the supported tx/rx chainmask values?
I was thinking we should register with supported values, instead of configured values. That is the intention of the code. In case we ever re-register after user has configured the system, this should retain that functionality. If it is impossible to re-register the wiphy, then this extra use_cfg_chains logic could go away. On startup, before user ever configures anything (and most users never will), the cfg-tx-chainmask is 0, so it would stay with chip's defaults. Thanks, Ben
