The modules I received at the end of November 2019 are version 1.0 and do not support jumbo frames. There is a later iteration with vendor version 2.16 that supports jumbo frames. Apparently the 2.16 versions have been around for a while, so wherever they're coming from, they're really out of date. Mine is coming back, I won't spend $150 on something that doesn't have essential networking features.
