[Bridge] max number of enslaved devices
What is the maximum number of devices that can be enslaved in a bridge interface? I have tried enslaving 512 devices. Although the brctl tool did not complain while adding them, when I use brctl show command it only shows 255. Thanks

[BRIDGE]A basic question: what's the relationship of the Rx/Tx packets count between the bridge and its enslaved NIC.
...0 br0: 51341 341 0 0 0 0 0 0 35324 277 0 0 0 0 0 0 I wonder the meaning of the value of the br0, it's Rx/Tx packets is less than both eth0 and eth1. what's the relationship of the values between bridge and it's enslaved NIC? Thanks for your comments on this.

[Bridge] Bridge and PACKET-socket
Ahoy, I've encountered some confusing semantics with using PACKET(7) sockets on bridge-enslaved interfaces. Specifically, if my socket accepts all types of frame (bind() to ETH_P_ALL) then it gets all packets; but if it accepts any specific type (e.g. ETH_P_IP), then it receives no packets at all. That is how it's coded in net/core/dev.c's netif_receive_skb(). First ETH_P_ALL handler...

CentOS 5.7 Ethernet bonding - order of enslavement matters?
Setting up bonding in active-backup mode 1 (using ARP monitoring) on a server, it looked OK, but pulling the active link cable didn't actually work, it didn't fail over. Eventually with manual playing around with modprobe, ifconfig, ifenslave, etc., a solution was stumbled upon: enslave the eth1 device before eth0, and all is good. Why this should matter is a puzzle - I could not find

[Bridge] Sniffing a linux bridge vs sniffing enslaved interfaces
Hi all Assume that you have a linux bridge with two interfaces eth0 and eth1 enslaved to this bridge What is the difference between sniffing the bridge and sniffing its interfaces? tcpdump -i br0 vs tcpdump -i eth0 Thanks MiniME -------------- next part -------------- An HTML attachment was scrubbed...

[RFC PATCH] virtio_net: Extend virtio to use VF datapath when available
...show up as "ethN_vf" on Hyper-V which is user friendly. > > Patch is pending. While it's good to show VF with specific naming to indicate enslavement, I wonder wouldn't it be better to hide this netdev at all from the user space? IMHO this extra device is useless when being enslaved and we may delegate controls (e.g. ethtool) over to the para-virtual device instead? That way it's possible to eliminate the possibility of additional udev setup or modification? I'm not sure if this is consistent with Windows guest or not, but I don't find it _Linux_ user friendly th...

[Bridge] device eth0 is already a member of a bridge; can't enslave it to bridge Net6
Hello, I am working on Network-Simulation (VNUML). Our simulator uses linux bridgi= ng to connect the UMLs. So there is one problem: The example is the following: There are two hosts simulating one big net. The two hosts have connection over the external nets Net3 and Net6 (see htt= p://www.uni-koblenz.de/~timbub/verteilteSim3.GIF), but in fact there is onl= y one physical connection between the
