PF_RING DNA RSS in libpcap

I've just made a little patch to enable the PF_RING_DNA_SYMMETRIC_RSS
flag if the environment variable PCAP_PF_RING_DNA_RSS exists:

--- userland/libpcap-1.1.1-ring/pcap-linux.c.orig 2012-06-05
08:32:28.000000000 +0100
+++ userland/libpcap-1.1.1-ring/pcap-linux.c 2012-07-11
15:27:10.434677526 +0100
@@ -1167,6 +1167,7 @@
int flags = 0;

if(handle->opt.promisc) flags |= PF_RING_PROMISC;
+ if(getenv("PCAP_PF_RING_DNA_RSS")) flags |=
PF_RING_DNA_SYMMETRIC_RSS;

handle->ring = pfring_open((char*)device, handle->snapshot,
flags);

Then checked with PF_RING-enabled tcpdump

PCAP_PF_RING_DNA_RSS=yes tcpdump -n -i dna0@3

and now the flows are nicely symmetric :)

Best Wishes,
Chris
