That PTP support was mostly self-contained code that installed some rules to replicate PTP packets on the CPU queue, in felix_setup_mmio_filtering(). However ocelot-8021q starts to look more interesting for general purpose usage, so it is now time to reduce the technical debt by integrating the PTP traps used by Felix for tag_8021q with the rest of the Ocelot driver. There is further consolidation of traps to be done. The cookies used by MRP traps overlap with the cookies used for tag_8021q PTP traps, so those features could not be used at the same time. ==================== Signed-off-by: David S.
