As part of this PR#sonic-net/sonic-buildimage#4412
we have added ACCEPT rules for BGP packets as default. Because of this
my earlier change of iptable rule added in qos_sai.yml to Drop BGP packets get ignored because of lower priority
and make test case fails since BGP packets impacts Buffer calculation assumption of testcases.
Fix is to add iptable rule to Drop BGP Packet from test case as highest
priority.
During cleanup highest priority rule will get deleted first.
