An issue while working with P2P

 The x call back in ieee80211_ops has a return void. In case of CMD_FRAME , I  would assume it translates to tx call back so I think the ENOSYS may have been called by some module above the driver which corresponds to  this error ?

That would be my assumption. I suppose there's a slight chance of something going wrong in the syscalls or something, but that seems like a stretch. Better look for -ENOSYS in the driver first.
