Hi 

 

I noticed that there is a patch which can set hardware timestamp for the
received
packets(http://www.wand.net.nz/trac/libtrace/browser/Intel%20DPDK%20Patches/
hardware_timestamp.patch?rev=ce7153dbc6a13c18bf8033af08c1249527754168), but
it only works in e1000 and igb NICs. I want to capture packets with
timestamp info in 82599 NICs, what should I do? Could you give me some help?

 

Thanks.
