On a running system, how do I determine which SATA speed (1.5/3/6) the
disk are currently connected at?

I found this:
https://www.cyberciti.biz/faq/linux-command-to-find-sata-harddisk-link-speed/

None of the methods described work :-( (dmesg, smartctl,
hdparm, /sys/class/ata_link/*/sata_spd ).

$ cat /sys/class/ata_link/link*/sata_spd
6.0 Gbps
1.5 Gbps
<unknown>
<unknown>
$ dmesg | grep 'SATA link'
[ 1.626512] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 1.626558] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)

Leap 15.0

The boards have an ICH7R controller which is 3Gbps, so I'm pretty
certain about the speed, but surely there is a way to tell?
