Description

ipfwd/test_mtu.py fails due to "AttributeError: 'SubRequest' object has no attribute 'param'". This issue seems to have started after https://github.com/sonic-net/sonic-mgmt/pull/6084 - which was introduced on August 23. We see the test case last passing on August 15th.

@abdosi - are we supposed to add some variable in inventory file or pass something while running the nightly - Kindly let us know
