virtchnl: Add header dependencies

2023-10-05T16:13:42Z

The uses BIT, struct_size and ETH_ALEN macros but does not include appropriate header files that defines them. Add these dependencies so this header file can be included anywhere.

virtchnl: Add CRC stripping capability

2023-09-13T15:50:49Z

Some VFs may want to disable CRC stripping on incoming packets so create an offload for that. The VF already sends information about configuring its RX queues so use that structure to indicate that the CRC stripping should be enabled or not.

virtchnl: fix fake 1-elem arrays for structures allocated as `nents`

2023-08-16T16:14:14Z

Finally, fix 3 structures which are allocated technically correctly, i.e. the calculated size equals to the one that struct_size() would return, except for sizeof(). For &virtchnl_vlan_filter_list_v2, use the same approach when there are no enough space as taken previously for &virtchnl_vlan_filter_list, i.e. let the maximum size be calculated automatically instead of trying to guestimate it using maths.

virtchnl: fix fake 1-elem arrays in structures allocated as `nents + 1`

2023-08-16T16:05:04Z

There are five virtchnl structures, which are allocated and checked in the code as `nents + 1`, meaning that they always have memory for one excessive element regardless of their actual number. This comes from that their sizeof() includes space for 1 element and then they get allocated via struct_size() or its open-coded equivalents, passing the actual number of elements. Expand virtchnl_struct_size() to handle such structures and replace those 1-elem arrays with proper flex ones. Also fix several places which open-code %IAVF_VIRTCHNL_VF_RESOURCE_SIZE. Finally, let the virtchnl_ether_addr_list size be computed automatically when there's no enough space for the whole list, otherwise we have to open-code reverse struct_size() logics.

virtchnl: fix fake 1-elem arrays in structs allocated as `nents + 1` - 1

2023-08-16T15:56:56Z

The two most problematic virtchnl structures are virtchnl_rss_key and virtchnl_rss_lut. Their "flex" arrays have the type of u8, thus, when allocating / checking, the actual size is calculated as `sizeof + nents - 1 byte`. But their sizeof() is not 1 byte larger than the size of such structure with proper flex array, it's two bytes larger due to the padding. That said, their size is always 1 byte larger unless there are no tail elements -- then it's +2 bytes. Add virtchnl_struct_size() macro which will handle this case (and later other cases as well). Make its calling conv the same as we call struct_size() to allow it to be drop-in, even though it's unlikely to become possible to switch to generic API. The macro will calculate a proper size of a structure with a flex array at the end, so that it becomes transparent for the compilers, but add the difference from the old values, so that the real size of sorta-ABI-messages doesn't change. Use it on the allocation side in IAVF and the receiving side (defined as static inline in virtchnl.h) for the mentioned two structures.

virtchnl: i40e/iavf: rename iwarp to rdma

2023-01-25T16:55:19Z

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/' perl -p -i -e 's/_iwarp/_rdma/' 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.

virtchnl: do structure hardening

2023-01-25T16:55:19Z

The virtchnl interface can have a bunch of "soft" defined structures hardened by using explicit sizes for declarations, and then referring to the enum type that uses them in a comment. None of these changes should change any of the structure sizes. Also, remove a duplicate line in a switch statement and let two cases uses the same code.

virtchnl: update header and increase header clarity

2023-01-25T16:55:19Z

We already have the SPDX header, so just leave a copyright notice with an updated year and get rid of the boilerplate header (so 2002!). In addition, update a couple of comments to clarify how the various parts of the virtchannel header interaction work. No functional changes.

Add new VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC flag, opcode VIRTCHNL_OP_GET_SUPPORTED_RXDIDS and add member rxdid in struct virtchnl_rxq_info to support AVF Flex RXD extension. Add support to allow VF to query flexible descriptor RXDIDs supported by DDP package and configure Rx queues with selected RXDID for IAVF. Add code to allow VIRTCHNL_OP_GET_SUPPORTED_RXDIDS message to be processed. Add necessary macros for registers.
