Hello, what do you mean by “That version is no longer supported” in the context of “an old MFT version for ConnectX-3 (MFT 4.9)”?
According to a different thread, there is still a plan of releasing support on new kernel version:
The name ‘LTS’ should also suggest a long turn support commitment, isn’t it?
However, I do wish somebody inside the company can update on a more clear release schedule.
The other thread promised a new release on June will get Debian 11.2 covered (5.10 based kernel).
And June is about to leave now :-)
