The AltiVec header file breaks boolean type. [1] [2] Currently the workaround was located only in mlx5 device. Adding the trace module caused this issue to appear again, due to order of includes, it keeps overriding the local fix.
This patch solves this issue by resetting the bool type, immediately after it is being changed.
