Known issues

Category	Description
Network configuration	Order of operations: Network configuration should be done bottom-up, teardown should be done top-down
ACL	ACL key size: Rules that match on L2 fields and the complete IPv6 header cannot be specified
L3 routing	ECMP size: The current supported ECMP size is 32 next hops
Miscellaneous	During boot PCIe driver complains about a Non-Fatal error. Device functionality is not impacted
Firmware bug	Generating traffic from host where MTU >= 5k would eventually cause the firmware to get stuck. Possible WA: Manually update firmware to 13.1530.152
