Approach
What is the motivation for this PR?
Fix the dualtor io failure:
The issue is introduced by PR #18299.
The reason is that, the dualtor sniffer now listens to all dataplane interfaces on ptf (with prefix
eth); for topo likedualtor-120, it has 128 dataplane interfaces, dualtor sniffer takes up to 10+ seconds to setup 128 sockets for those interfaces, which can takes up to 10+ seconds.Signed-off-by: Longxiang Lyu lolv@microsoft.com
How did you do it?
As now
scapydefaults to listen onconf.iface(on ptf, it is mgmt) and it will usesocket.bindto bind to it, let's replacesocket.bindwith a dummy NOOP function, so the packet socket created will not listen toconf.ifaceanymore and it will capture packets from all interfaces.How did you verify/test it?
On dualtor-120:
Any platform specific information?
Supported testbed topology if it's a new test case?
