Description of PR
Summary:
Backport sonic-net/sonic-mgmt#26777 to the internal 202512 branch. Prevent LT2 ACL table creation from binding physical interfaces that are already members of PortChannels.
Fixes sonic-net/sonic-mgmt#26777
Type of change
Back port request
Approach
What is the motivation for this PR?
LT2 ACL setup can include physical interfaces that are already PortChannel members, causing invalid duplicate ACL bindings.
How did you do it?
Collected PortChannel members by namespace and excluded those interfaces when adding standalone upstream RIFs to the ACL table.
How did you verify/test it?
Resolved the 202512 cherry-pick conflict by retaining only the intended LT2 change. Verified the resulting diff and Python syntax.
Any platform specific information?
Applies to LT2 topologies.
Supported testbed topology if it's a new test case?
N/A; this is a fix to an existing ACL test.
