106 IBM System z Personal Development Tool: Volume 3 Additional Topics
statements. The --unitadd parameter is used in the devmap because the default OSA unit
addresses
3
would be 20 and 21 (using the two low-order digits of the device number) and we
want unit addresses 0 and 1.

10.3 More complete QDIO example
We used the find_io command to determine that our Ethernet adapter was eth0, and that it
was assigned as CHPID F0. The tunnel interface is always CHPID A0. We elected to use the
QDIO mode for both OSA interfaces. We used the following devmap:

3
This unit address is the (emulated) hardware address within the (emulated) OSA control unit. It is not the device
number (“address” in common terminology).
4
The default OAT used by OSA requires unit addresses 0 and 1 for TCP/IP when in OSE mode.
