IEE1588/PTP support for NIC drivers ?

[Olivier Cochard-Labbé]

Hi,

Some network cards support IEE1588 hardware timestamp (like some Intel
card), but their drivers didn't support this feature.
I beleive there is a kernel feature missing for this suppport.

Searching on the archive's mailing-list, I've found this post about some
legal issue:

Is still a legal problem or just a missing feature ?

Thanks,

Olivier
