Subject: [PATCH v1 0/2] ptp: Add generic header parsing function

Hi,

in order to reduce code duplication in the ptp code of DSA drivers, move the
header parsing function to ptp_classify. This way the Marvell and the hellcreek
drivers can share the same implementation. And probably more drivers can benefit
from it. Implemented as discussed [1] [2].

@DSA maintainers: Please, have a look the Marvell code. I don't have hardware to
test it. I've tested this series only on the Hirschmann switch.

Thanks,
Kurt
