Subject: [PATCH v4 0/9] ptp: Add generic helper functions

Hi!

in order to reduce code duplication (and cut'n'paste errors) in the ptp code of
DSA, Ethernet and Phy drivers, create helper functions and move them to
ptp_classify. This way all drivers can share the same implementation.

This is version four and contains bugfixes. Implemented as discussed [1] [2]
[3] [4].

Previous versions can be found here:

Thanks,
Kurt

 * Fix msgtype offset for ptp v1 packets

Changes since v1:

 * Fix Kconfig (Richard Cochran)
