Test whether the given link is online
bool ata_link_online(struct ata_link * link);
link
ATA link to test
Test whether link is online. This is identical to ata_phys_link_online when there's no slave link. When there's a slave link, this function should only be called on the master link and will return true if any of M/S links is online.
None.
True if the port online status is available and online.
