In TMSH documentation associated with /ltm profile fastl4's pva-offload-state attribute, the text refers to "TCP CSYN" and "UDP CS". What are these two terms?

can you just show the full text you get? mine says pva-offload-state Specifies at what stage the ePVA performs hardware offload. embryonic implies TCP SYN or first UDP packet, establish implies 3WAY handshaking or CS round trip confirmed. so i see no TCP CSYN, but regular SYN. i do see CS, which might be Client Side. in any case i assume it means it will only be offloaded if there has been a UDP response.
