Change DHCP rate limit in SONiC copp configuration to 100 PPS as this is necessary to ensure that DHCP flood does not cause LACP/BGP flaps in all scenarios This is an extension to the change in image_config: copp: Enable rate limiting for bgp, lacp, dhcp, lldp, macsec and udld #14859 and sonic-mgmt change in [tests/copp]: Update copp mgmt tests to support new rate-limits sonic-mgmt#8199 Why I did it 300 PPS is not sufficient to prevent LACP/BGP flaps in all cases. 100 PPS seems to provide better resiliency against DHCP traffic flood to CPU. Microsoft ADO 25776614: Send DHCP broadcast packets to DUT and verify that they are trapped to CPU at 100 PPS. Signed-off-by: Prabhat Aravind <paravind@microsoft.com>
