net: ptp: do not reimplement PTP/BPF classifier
There are currently pch_gbe, cpts, and ixp4xx_eth drivers that open-code and reimplement a BPF classifier for the PTP protocol. Since all of them effectively do the very same thing and load the very same PTP/BPF filter, we can just consolidate that code by introducing ptp_classify_raw() in the time-stamping core framework which can be used in drivers. As drivers get initialized after bootstrapping the core networking subsystem, they can make use of ptp_insns wrapped through ptp_classify_raw(), which allows to simplify and remove PTP classifier setup code in drivers. Joint work with Alexei Starovoitov.
