I burnt a mem-free f/w on the card and this time I'm getting a different
error when trying to set num_mtt to 2097152.
I did:
modprobe ib_mtcha num_mpt=262144 num_mtt=2097152
logs:

Roland, when your attempt succeeded were you using a mem-free HCA or the
256MB version?
devinfo whit the mem-free f/w.
