I believe (but could be wrong) that vendor specific metadata is referring to raid metadata that commercial raid vendors put on drives. MD is able to understand that data and assemble arrays based on it (and avoid overwriting it)

This is *damn* good because it means that if your proprietary RAID card
dies, md can get the data off the disks again. (It can probably do it anyway with RAID-5 as long as you remember the stripe size, as there aren't many ways to arrange a RAID-5 array. But RAID-6 is harder.)
