Intel GigE NIC Issue on IPv6 DAD

2010-02-08 Thread Siquijor Philips
Hi, I'm currently doing IPv6 conformance testing with FreeBSD-7.1 RELEASE however I've encountered DAD timing issue on Intel Gigabit NICs with em(4) driver. I configure several tweaks on net.inet6.ip6.dad_count such as 2 seconds, 3 seconds and 4 seconds just to get the specific DAD timing on each

intel 82576 ipsec offload?

2009-10-07 Thread Siquijor Philips
Hi, I got a dual-port Intel Gigabit NIC with 82576 (ET) chipset http://www.intel.com/Assets/PDF/prodbrief/320116.pdf. It has a feature on IPsec offloading but it only mentioned Microsoft Windows 2008 and Vista servers. I wonder if FreeBSD have also support on this feature? Thanks, Siquijor __

Questions on processing smaller frame size

2009-02-24 Thread Siquijor Philips
Can someone explain why FreeBSD network throughput (both incoming and outgoing traffic) decreases when smaller frame size being processed? With smaller frame size, corresponding packet rate (packet/sec or pps) increases and experiencing dropped packets. What causes dropping of packets with small fr

PF with TSO

2009-01-18 Thread Siquijor Philips
Hi, FreeBSD-7.1 is shipped with TCP segmentation offload (TSO) feature to some network interface cards by default such as Intel and Broadcom. I would like to know if there's any impact when PF is enabled together with TSO in terms of performance and packet inspection? Thank you, Regards, Siquijo
