This commit adds the Kconfig mechanism and the pfilter rules. The latency test socket transmists frames of a specific ether type; the receiver must receive all such frames. To minimize the load on the packet filter, this adds a single rule: we already accept all PTPv2 frames, so we now "OR" to this the new ethernet type. If the feature is configured off, the rule uses the same PTPv2 ethertye, thus turning in practice into a NOP. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
