Hi, Upstream removed support for CX3 cards in commit 52eb6c0ebbe8ad585da2a00c751260a025ad3f20: https://github.com/Mellanox/mstflint/issues/1157
And it look like they never merged a patch to warn the user of this issue. So every release after 4.26.0-1 will have this issue. The only resolution would be to package msflint 4.25.0-1 as msflint-cx3 like it is done for ssh1 compatibility. Best regards, NS
