X-Git-Tag: v2.6.39-400.9.0~423^2~19^2~11^2~256

igb: enable l4 timestamping for v2 event packets

When enabling hardware timestamping for ptp v2 event packets, the
software does not setup the queue for l4 packets, although layer 4
packets are valid for v2. This patch adds the flag which enables
setting up a queue and enabling udp packet timestamping.
