[PATCH 0/4] Extend Time Stamping

[Richard Cochran <richardcochran@gmail.com>]

This patch set extends the packet time stamping capabilites of the
network stack in two ways.

1. The first patch presents a work-around for the TX software time
   stamping fallback problem cited in cd4d8fdad1f1. The idea is to add
   two inline functions into each MAC driver. The functions act as
   hooks which are only present if certain CONFIG options are enabled.

2. The other patches prepare the way for PHY drivers to offer time
   stamping.

I am preparing a new round of patches for PTP support, but it will
require the changes in this patch set in order to function. Thus I
would like to have this patch set reviewed (and hopefully merged) in
order to go forward.

Thanks,
Richard
