Subject: Use non-zero timeout in pcap_open_live
X-Git-Tag: release_2_2_0~186
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f4bb61eeab62d73aa0c33b4a174df20b83b66c76;p=thirdparty%2Ffreeradius-server.git

Use non-zero timeout in pcap_open_live

http://www.tcpdump.org/pcap.html says:

  to_ms is the read time out in milliseconds (a value of 0 means
  no time out; on at least some platforms, this means that you may
  wait until a sufficient number of packets arrive before seeing
  any packets, so you should use a non-zero timeout)

Nice..
