Hi,
I have a user space application, that puts eth0 into bridge br0. At
this moment all connections seem frozen. Telnet, HTTP, and NFS.
For development i have nfs root fs.
There is a ioctl() that does the equivalent of "brctl addif br0 eth0"
That cuts all the connections for a few seconds.
nfs: server 192.168.10.51 not responding, still trying
br0: topology change detected, propagating
br0: port 1(eth0) entering forwarding state
nfs: server 192.168.10.51 not responding, still trying
nfs: server 192.168.10.51 OK
nfs: server 192.168.10.51 OK
Then everything is OK..
Is there anyway i can fix this, so my applicaion goes ahead at full speed?
using libnl i tried flushing the ARP cache on all devices, but it didn't
seem to help.
Thanks

turn off forwarding delay (unless you are using STP).
brctl setfd br0 0
