Since the latest Intel hardware does both IWARP and ROCE, rename the term IWARP in the virtchnl header to be RDMA. Do this for both upper and lower case instances. Many of the non-virtchnl.h changes were done with regular expression replacements using perl like: perl -p -i -e 's/_IWARP/_RDMA/' <files> perl -p -i -e 's/_iwarp/_rdma/' <files> and I had to pick up a few instances manually. The virtchnl.h header has some comments and clarity added around when to use certain defines. note: had to fix a checkpatch warning for a long line by wrapping one of the lines I changed.

/* Description:
|
|
* This header file describes the Virtual Function (VF) - Physical Function
|
|
* (PF) communication protocol used by the drivers for all devices starting
|
|
* from our 40G product line
|
|
*
|
|
* Admin queue buffer usage:
|
|
* desc->opcode is always aqc_opc_send_msg_to_pf
|
|
* flags, retval, datalen, and data addr are all used normally.
|
|
* The Firmware copies the cookie fields when sending messages between the
|
|
* PF and VF, but uses all other fields internally. Due to this limitation,
|
|
* we must send all messages as "indirect", i.e. using an external buffer.
|
|
*
|
|
* All the VSI indexes are relative to the VF. Each VF can have maximum of
|
|
* three VSIs. All the queue indexes are relative to the VSI. Each VF can
|
|
* have a maximum of sixteen queues for all of its VSIs.
|
|
*
|
|
* The PF is required to return a status code in v_retval for all messages
|
|
* except RESET_VF, which does not require any response. The returned value
|
|
* is of virtchnl_status_code type, defined here.
|
|
*
|
|
* In general, VF driver initialization should roughly follow the order of
|
|
* these opcodes. The VF driver must first validate the API version of the
|
|
* PF driver, then request a reset, then get resources, then configure
|
|
* queues and interrupts. After these operations are complete, the VF
|
|
* driver may start its queues, optionally add MAC and VLAN filters, and
|
|
* process traffic.
