Category	Description
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"
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
Spectrum-2	Currently raising the link at 10/40Gb/s link speed is not supported when using 200Gb/s optical cables
SN3800	Split 4x25GbE not supported
SN3800	Cisco Bidi module is currently not supported
SN3800	Link is down after a few link toggles when using the MMA1B00-C100D 100G transceiver
SN3800	InfiniBand optical cables are currently not supported
SN3800	Currently raising the link at 25Gb/s / 100Gb/s link speed is not supported when using 200GbE copper cables
SN3800	Connectivity to a 3rd party switch systems may not go up when using copper and optical cables
SN3800	Traffic can be dropped due to high BER in link. Workaround: toggle the link
SN3800	High effective BER occurs when using optical and copper cables with 100GbE link speed
SN3800	Auto-negotiation not supported. When user sets "autoneg on", the actual configuration is force of highest supported speed
SN3700	At 200GbE speed, traffic drop occurs between SN3700 and IXIA
SN3700	200GbE optical cables are not supported
Clock	clocksource refined-jiffies is broken, clock is stuck. Many commands are impacted - sleep, date, ping, etc. To solve it - edit /etc/default/grub, add "tsc=reliable clocksource=tsc" to GRUB_CMDLINE_LINUX
SN5600	When connecting NVIDIA-to-NVIDIA in PAM4 (system default) using DAC, Auto-Neg should always be enabled.
