On any distro release, the lsqeth utility from the s390-tools package 
can display the card_type. This attribute contains the link speed, but 
only for real OSA, i.e. dedicated / direct-attached to z/VM guests.

In my following example, I used a dedicated OSA with 1Gbps Ethernet.
# lsqeth
Device name                     : eth0
---------------------------------------------
        card_type               : OSD_1000
...

Please find documentation of possible card_type values in
http://public.dhe.ibm.com/software/dw/linux390/docu/l26edd01.pdf, "qeth" 
chapter (page 107) -- or alternatively any other recent device drivers 
book (the older version matching SLES 10 did not yet document the 
card_type attribute).

If you use virtual OSA, i.e. through z/VM VSWITCH, then you would have 
to check the link speed of the VSWITCH uplink OSA(s) (RDEV(s) and/or 
portgroup) under z/VM.

I don't know which source velocity uses to determine the network (link) 
speed, but the above described method should provide reliable 
information directly from the qeth device driver.
