Subject: igb: enable l4 timestamping for v2 event packets
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=11ba69e876e1141fa4b11a7c0efb256a8df9ae7d;p=~shefty%2Frdma-dev.git

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.
