Thank you for your suggestion. 
The Cadence GEM hardware I'm using supports both IPv4 and IPv6 TSO.
However, I'm uncertain whether the driver's initial support only for
IPv4 TSO implies that older hardware versions exist which solely support
IPv4 TSO.

Regarding the identity verification, "zuoqian" is indeed my legal full
name.
