It is not.  5.2 has an ATA_LBA48 flag, going with the flags field of
struct ata_bio, but no LBA48 flag for ata_command.flags.

My evolution of 5.2 has AT_READREG48, which I added as part of my
attempt to support HPAs.  But that's the closest thing I see, and
that's not really close enough to be useful here.

And presumably the NetBSD wdccommand/wdccommandext difference matches
the FreeBSD one closely enough for that to be relevant?  I shall have
to read wdccommand* over in more detail.
