[dpdk-dev] [PATCH v3] ethdev: cleanup device ops struct whitespace

[Ferruh Yigit <ferruh.yigit@intel.com>]

- 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
- Moved some comments to same line if overall line < 100 chars

- ! 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:
