From de4aee7d69f2957c808572f2d5b5fc808ebe212a Mon Sep 17 00:00:00 2001 From: Fan Du Date: Fri, 3 Jan 2014 11:18:30 +0800 Subject: {pktgen, xfrm} Using "pgset spi xxx" to spedifiy SA for a given flow User could set specific SPI value to arm pktgen flow with IPsec transformation, instead of looking up SA by sadr/daddr. The reaseon to do so is because current state lookup scheme is both slow and, most important of all, in fact pktgen doesn't need to match any SA state addresses information, all it needs is the SA transfromation shell to do the encapuslation. And this option also provide user an alternative to using pktgen test existing SA without creating new ones.
