[dpdk-dev] [PATCH v14 0/8] ethdev: 100G and link speed API refactoring

[Marc Sune]

From: Marc Sune <marc at voltanet.io>

This series of patches adds the following capabilities:

* speed_capa bitmap in rte_eth_dev_info, which is filled by the PMDs
  according to the physical device capabilities.
* refactors link API in ethdev to allow the definition of the advertised
  link speeds, fix speed (no auto-negociation) or advertise all supported
  speeds (default).

v14:
    - Rebase to master HEAD
    - Add ETH_LINK_FIXED / ETH_LINK_AUTONEG MACROs in rte_ethdev.h
    - Fix NFP speed capability (50G -> 40G)
    - Fix ixgbe full AUTONEG

v13:
    - Fix startup regression; revert flip of ETH_LINK_SPEED_FIXED and
      ETH_LINK_SPEED_AUTONEG values. ETH_LINK_SPEED_AUTONEG is now 0.
    - Fix incorrect duplex link reporting for e1000.
    - Do not allow more than one speed in the bitmap when
      ETH_LINK_SPEED_FIXED is used for e1000.

v12:
    - rebase on 16.04-rc2
    - fix mlx capabilities
    - update ENA driver

v11:
    - rebase on 16.04-rc1
    - replace on more link status value in e1000 driver
    - merge szedata2 patches
    - remove szedata2 temporary comments in code and doc

v10:
    - rebase
    - rework release notes
    - rearrange patch splitting
    - fix doxygen comments
    - fix typos
    - removed log format of link.link_speed as %d (keep %u)
    - complete ETH_LINK_[DOWN/UP] replacement from 0/1
    - change ETH_LINK_SPEED_AUTONEG to 1
    - replace ETH_LINK_SPEED_NEG by ETH_LINK_SPEED_AUTONEG (1)
    - replace ETH_LINK_SPEED_NO_AUTONEG by ETH_LINK_SPEED_FIXED (0)
    - rework rte_eth_speed_to_bm_flag to rte_eth_speed_bitflag
    - complete 100G support in testpmd

v9: rebased to current HEAD. Reverted numeric speed to 32 bit in struct
    rte_eth_link (no atomic link get > 64bit). Fixed mlx5 driver compilation
    and link speeds. Moved documentation to release_16_04.rst and fixed several
    issues. Upgrade NIC notes with speed capabilities.

v8: Rebased to current HEAD. Modified em driver impl. to not touch base files.
    Merged patch 5 into 3 (map file). Changed numeric speed to a 64 bit value.
    Filled-in speed capabilities for drivers bnx2x, cxgbe, mlx5 and nfp in
    addition to the ones of previous patch sets.

v7: Rebased to current HEAD. Moved documentation to v2.3. Still needs testing
    from PMD maintainers.

v6: Move link_duplex to be part of bitfield. Fixed i40 autoneg flag link
    update code. Added rte_eth_speed_to_bm_flag() to .map file. Fixed other
    spelling issues. Rebased to current HEAD.

v5: revert to v2 speed capabilities patch. Fixed MLX4 speed capabilities
    (thanks N. Laranjeiro). Refactored link speed API to allow setting
    advertised speeds (3/4). Added NO_AUTONEG option to explicitely disable
    auto-negociation. Updated 2.2 rel. notes (4/4). Rebased to current HEAD.

v4: fixed errata in the documentation of field speeds of rte_eth_conf, and
    commit 1/2 message. rebased to v2.1.0. v3 was incorrectly based on
    ~2.1.0-rc1.

v3: rebase to v2.1. unified ETH_LINK_SPEED and ETH_SPEED_CAP into ETH_SPEED.
    Converted field speed in struct rte_eth_conf to speed, to allow a bitmap
    for defining the announced speeds, as suggested M. Brorup. Fixed spelling
    issues.

v2: rebase, converted speed_capa into 32 bits bitmap, fixed alignment
    (checkpatch).
