This is just the first file - similar optimization will be done
on other MADs receivers.
Note that this patch doesn't mess with all the non-fatal cases.
The goal was not to help SM to perform better with all the
validations that it does, but to make sure that the fatal
cases will never be predicted wrong, so any fatal check (existing
or a newely added one) won't affect the SM performance.
