Subject: [PATCH net-next 0/2] Transmit time stamping on tun/tap interfaces

From: Richard Cochran <[email-masked]>
Date: Fri, 19 Jul 2013 19:40:08 +0200

This series adds transmit SO_TIMESTAMPING for tun and tap devices.
Having this support is useful for testing multiple instances of PTP
programs (for example, to exercise the best master clock behavior)
and for synchronizing virtual guests.

The first patch refactors the code that delivers raw error queue
packets into a common function, in order to avoid multiple, nearly
identical implementations. This can be used whenever a network layer
has an error queue for transmit time stamp reporting only.

Thanks,
Richard

Richard Cochran (2):
  Provide a generic socket error queue delivery method for Tx time
    stamps.
  tun: Support software transmit time stamping.
