If the lanes are locked and not generating CRC-32 errors, you can exchange traffic.
If IDLE symbols pass, but regular traffic generates numerous CRC-24 errors, the
lanes might be out of order. IDLE symbols are single word messages and therefore
not subject to ordering issues. However, multi-word messages generate CRC-24
errors when the lanes are out of order. Due to manufacturing constraints, boards
and adapters are often designed with scrambled lane order. Check that your
physical connections take these lane order differences into account.
