  - Grouped related items using empty lines
- Aligned arguments to same column
- All item comments that doesn't fit same line are placed blow the item
  itself

- ! This patch has the problem of trashing the git history for the struct,
  which is indeed valid argument.
- Some re-ordering also may be required which I hesitate to do
- Some item comments doesn't give extra information and can be removed

v3:
- group MAC, MTU, promisc and allmuti functions together
- group rxq/txq_info_get with dev_infos_get
- group l2_tunnel_* and udp_tunnel_* functions together

v2:
- extract mtu_set into new group
- move rss_hash_* to reta_* group
- move set_mc_addr_list to mac_addr_* group
- move set_vf_rate_limit to set_vf_* group
- move get_dcb_info out of timesync_* group

To make it easy to comment to latest struct, copy-paste here:

Reordering fields of a struct is breaking ABI. We should bump the
library version now.

You are right, sorry missed that.
Intention was not to break the ABI, but cleanup.

If it is too late, do you want me prepare a revert patch?

No
Please check doc/guides/rel_notes/deprecation.rst
We are going to break the ethdev ABI anyway.
