The drivers appears to load ok in beta 30. However, my card fails during the init and gives an error. The card shows as a TN9710P, when downloading the source code for the drivers from the Tehuti site, they have a message indicating you will need a separate firmware file.
I expect I need the "x3310fw_0_3_4_0_9445.hdr firmware" which was included in 6.8. https://forums.unraid.net/topic/86028-unraid-os-version-68-available/
