G.3.1 FUNCTION identifier

The FUNCTION identifier (FID) is a hexadecimal number between 000 and FFF that you use
to assign a PCHID to the FUNCTION to identify the specific hardware feature in the PCIe I/O
drawer. Because the FUNCTION is not related to a channel subsystem, all LPARs on a CPC
can be defined to it. However, a FUNCTION cannot be shared between LPARs. It is only
dedicated or reconfigurable by using the PART parameter. The TYPE parameter is new for
z13s and is required.
G.3.2 Virtual function number
If you want several LPARs to be able to use a zEDC Express feature (the 10GbE RoCE
Express feature cannot be shared between LPARs), you need to use a virtual function (VF)
number. A
LPARs that the feature supports, which is 15 for the zEDC Express feature and 31 for the
RoCE Express feature.
G.3.3 Physical network identifier
The physical network identifier (PNETID) is required to set up the Shared Memory
Communications over RDMA (SMC-R) communication between two 10GbE RoCE Express
features. Each FUNCTION definition supports up to four PNETIDs.
