It creates a root directory directly in the the root of the debugfs filesystem and within that directories for each device, named after the device ID of the devices iwlwifi is attached to. In the cfg80211/mac80211 directory there's now a link to the toplevel iwlwifi debugfs directory to make it easier to find the debugfs files.

We almost never need to the Host Command that was sent while handling its response, but when we do need it, we see that the command has been modified. This mystery has been elucidated. The FH (our DMA engine) writes its meta data on the buffer in the DRAM. Of course it copies the buffer to the NIC first. This was known to happen for Tx command, but as a matter of fact, it happens to all TFD brought by the FH which doesn't care much about what it brings from DRAM to internal SRAM. So copy the Host Command to yet another buffer so that we can properly pass the buffer that was sent originally to the fw. Do that only if it was request by the user since very few flows need to get the HCMD sent in the response handler.
