Subject: Storing hardware timestamps - how about using the new skb's control block?

Hi,


Just a quick suggestion for storing hardware timestamps, how about

storing them in the new skb's control block?


From what I understand, any private users of the control block are

supposed to ignore the existing value, and if a protocol/tap is going

to be looking at the new skb, it should have done a skb_share_check()

first to grab it's own private copy if necessary, protecting the

control block stored timestamp value from any of the other skb

users who might change the control block value for their own purposes.


Regards,

Mark.
