How to not send traffic to TCP/IP stack

2021-01-29 Thread Kajetan Staszkiewicz
Hello group, On Linux traffic is directed to the IP stack by "local" entries in route table. By removing such entries, or rather not having them in the first place in additional routing tables it is possible to forward *all* traffic through a router, even if it is directed at router's own IP addre

Hi, Is there any plan to support KNI driver module in FreeBSD ? Also is FreeBSD support any open source TCP/IP stack at user space to be used along-with dpdk? Like F-stack or any other. Note: Got basic support info from https://wiki.freebsd.org/201511VendorDevSummit/HaveNeedWant Thanks

The FreeBSD-CURRENT TCP/IP Stack does not support D-SACK.

I view the TCP stack code of FreeBSD-CURRENT recently. It seems that current TCP/IP stack does not support D-SACK. Does someone will add D-SACK support in the future. Windows 7 and linux have add D-SACK supported. The detail of D-SACK is described in RFC2883
