PCIe function

A PCIe function is specified with the FUNCTION statement.

The FUNCTION statement contains the following keywords:

FID: Identifies the PCIe function within the processor configuration (mandatory).
TYPE: Identifies the PCIe function type (optional - defaults to ROCE).
UNIT: Identifies the PCIe function type (optional - support for backward compatibility).
PCHID: Identifies the PCIe adapter card which provides the specified function by specifying the slot of the card in the I/O drawer.
PORT: Identifies the port on the PCIe adapter (optional).
VCHID: Identifies a virtual PCIe adapter (exclusive to the PCHID keyword)
VF: Identifies the PCIe virtual function number (optional).
PNETID: Identifies the physical network IDs.
PART: Specifies the access and candidate lists of partitions entitled to use the PCIe function.
DESC: Specifies a description of the PCIe function (optional).
UID: Specifies a user defined identifier.

Table 1. PCIe Function Syntax
Syntax:
`FID=xxxx`	four hexadecimal characters
`TYPE=type`	valid PCIe function type
`UNIT=type`	PCIe function type (use to be backward compatible).
`PCHID=xxx`	three hexadecimal characters for physical channel id
`PORT=x`	one decimal digit
`VCHID=xxx`	three hexadecimal characters for virtual channel id
`VF=nnn`	up to three decimal digits
`PNETID=(pnetid1,…,pnetid4)`	up to four 16-character alphanumeric physical network IDs
`PART=(acc_lp1 [,(cand_lp1[,…,cand_lpn])])`	access list (limited to one partition) and optional candidate list of partitions connected to the PCIe function
`DESC='PCIe function description'`	up to 32 characters
`UID=xxxx`	up to four hexadecimal digits
