Also, as a heads up - just to get other peoples opinion here - I might prefer responding to such a flag by selecting the fallback cipher instead of actually implementing a workaround for my hardware in case such a workaround would be detrimental to the performance. > But you'll have to code this up, including the bit on the user-side > to actually set the flag. > Since that user side probably lives in the kernel tree too, I could do that. This would then apply to testmgr as well though, as I need to ensure it disables features for tests that don't require them. (otherwise you'd be verifying only the fallback cipher) Regards, Pascal
