Thanks for making it clearer. What about the open source atheros
firmware? Would it be a possible option to support those specific card
and fw (like ath9k_htc)?
regards,
Marco

I have a question regarding your comment, Richard. It might be worth moving
this to another thread.
PTP over WiFi is not supported in Linux for which reason? Is it due to WiFi
standard, linux driver or PTP implementation?
Time stamping on WiFi interfaces would require support in the Linux
kernel wireless stack. It would not be a huge change, but some work
would need to be done.
However, there is little point in doing this work. The fundamental
blocking issue is the proprietary firmware blobs running in the radio
chips. These would need to be changed to support such functionality.
Most likely we would need both the firmware source code and the
documentation of the radio chips themselves. Based on my industry
experience, I doubt anything will ever change in this particular area.
The blame lies squarely on the vendors of WiFi chips.
Sorry,
Richard
