netmap: how to bridge 2 eth?

Hi all I'm doing to implement a simple openflow-based software switch(not same as OVS, much simpler to OVS) and I choose netmap for the network framework Now I try to do a simplest thing: there's 3 VMs, all are Ubuntu 12.04.4 x64 2 act as hosts, other 1 act as switch topo: [host1] eth0 - e

Re: bridge Untagged packets on an interface

And also i tried ng_bpf + ng_eiface conjuction, but ng_bpf doesnt match "vlan" filter. With the script below, ng_bpf always calls ifNotMatch hook. When the pattern is "ip", ng_bpf matches frames have both vlan and ip headers. I think ng_bpf doesnt process ethernet header. Is there a way to proc

bridge Untagged packets on an interface

Hi, Assume that default vlan untagged and VLAN 10, 20, 30, 40 tagged on switch connected to em0 interface. i am trying to bridge only untagged frames on em0 with em1. Does if_vlan handle untagged frames? # ifconfig em0.0 create ifconfig: SIOCIFCREATE2: Invalid argument Any ideas? Best regards

9/STABLE Panic at netisr_dispatch_src w/ em(4) + PF

Hello, I am hoping someone can help me debug a kernel panic I have been experiencing on one of my production systems. The system is a PF+ALTQ firewall/gateway with about 1k simultaneous devices behind it at any given time, pushing no more than 100Mb/s of traffic. I have obtained a crash dump and t

Re: VLAN switching on freebsd

Thank you very much John, This approach is enlightened me. I'll try it. I couldnt think of use ng_vlan in front of ngeth nodes. I used openvswitch for this scenario, but performance is very very poor. I'm looking forward to release of the "in-kernel openvswitch on freebsd" project of Luigi Rizzo

VLAN switching on freebsd

Hi, i need to create a virtual interface that forwards only defined vlan tags. Lets talk on a sample scenario : Assume that VLAN 10, 20, 30, 40 tagged on switch connected to em0 interface. create ngeth0 and ngeth1. ( i dont need netgraph interface, it can be a any virtual interface tap .. etc. )

RX checksum offloading problem

Dear all, during testing I found that FreeBSD head (on a raspberry pi) accepts SCTP packet with bad checksums. After debugging this I figured out that this is a problem with the csum_flags defined in mbuf.h. The SCTP code on its input path checks for CSUM_SCTP_VALID, which is defined in mbuf.h:
