Mellanox Linux Switch 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
Multicast snooping	MDB records mapped to the same multicast MAC will share the same MDB record in the device.
	Deleting such records from the bridge driver will result in the following error being printed to the kernel log: "Unable to remove port from MC DB"
FRR	FRR 7.3+ installs routes using nexthop objects which are not supported by mlxsw, causing it to reject the routes. This can be fixed by the command no zebra nexthop kernel enable. The command is available in FRR 7.3.1 onwards. See this ticket for more details
Routing	When deleting an IP neighbour from user space, the neighbour transitions to FAILED state instead of being deleted completely. The neighbour is correctly deleted from the hardware data path and not marked with offload keyword. It can be deleted completely by issuing the deletion command again
Packet Drops Monitoring	Drop monitor needs to be built as built-in (CONFIG_NET_DROP_MONITOR=y) in order to report hardware drops
