Subject: [Intel-wired-lan][PATCH iwl-next v8 0/9] refactor IDPF resource 

Queue and vector resources for a given vport, are stored in the
idpf_vport structure. At the time of configuration, these
resources are accessed using vport pointer. Meaning, all the
config path functions are tied to the default queue and vector
resources of the vport.

There are use cases which can make use of config path functions
to configure queue and vector resources that are not tied to any
vport. One such use case is PTP secondary mailbox creation
(it would be in a followup series). To configure queue and interrupt
resources for such cases, we can make use of the existing config
infrastructure by passing the necessary queue and vector resources info.

To achieve this, group the existing queue and vector resources into
default resource group and refactor the code to pass the resource
pointer to the config path functions.

This series also includes patches which generalizes the send virtchnl
message APIs and mailbox API that are necessary for the implementation
of PTP secondary mailbox.

---
v8:
* rebase on AF_XDP series [1]
* drop one commit as it was no longer necessary
* add new commit ("idpf: remove vport pointer from queue sets")
to make recently introduced queue_sets compatible with resoure
refactor and corresponding API changes

v7:
* modify idpf_q_vec_rsrc declaration in idpf_vport struct to not
mess with memcpy in idpf_initiate_soft_reset
* reshuffle vport struct fields to avoid holes

v6:
* packed idpf_queue_id_reg_chunk struct
* fixed inconsistent use of caps/small case for kdoc
* initialized loop iterator inloop and used the right type
* moved adapter out of the loop in idpf_rxq_group_alloc

v5:
* update function parameters to pass chunks as needed
* revert back the 'idpf_is_feature_ena' changes
* remove redundant vport parameter in idpf_[add/del]_mac_filter
* refactor all send_virtchnl APIs to avoid accessing vport pointer
* refactor get_ptypes to avoid calling it for each vport

v4:
* introduce local idpf structure to store virtchnl queue chunks
* remove 'req_qs_chunks' field
* fix function doc comments to use caps or lower case letters

v3:
* update commit message of 6th patch

v2:
* fix kdoc issues (s/rss/RSS, add return statement)
* rename structure idpf_rsrc to idpf_q_vec_rsrc
* reshuffle struct members to avoid holes created in idpf_q_vec_rsrc and
idpf_vport structures
* introduce additional 2 patches to the series which generalizes the
send virtchnl message APIs and mailbox APIs
* fix unintialized usage of a variable in idpf_initiate_soft_reset
(reported by kernel bot)
