[dpdk-dev] [PATCH v2 00/15] common ethdev linkstatus functions

[Stephen Hemminger]

While writing the hyperv driver, noticed a lot of unnecessary
duplication of code in drivers for handling the eth_dev link status
information. While consolidating this, it also became obvious that
some drivers behave differently for no good reason.

It also was a good chance to introduce atomic exchange primitives
in EAL because there are other places using cmpset where not
necessary (such as bonding).

Mostly only compile tested only, don't have all of the hardware
available (except ixgbe and virtio) to test.

The difference from v1 is that function name changed, rebasing
to current source and the introduction of atomic exchange.

Stephen Hemminger (15):
  eal: introduce atomic exchange operation
  ethdev: add linkstatus get/set helper functions
  virtio: use eth_linkstatus_set
  vmxnet3: use rte_eth_linkstatus_set
  dpaa2: use rte_eth_linkstatus_set
  nfp: use rte_eth_linkstatus functions
  e1000: use rte_eth_linkstatus helpers
  ixgbe: use rte_eth_linkstatus functions
  sfc: use new rte_eth_linkstatus functions
  i40e: use rte_eth_linkstatus functions
  liquidio: use _rte_eth_linkstatus_set
  thunderx: use _rte_eth_linkstatus_set
  szedata: use _rte_eth_linkstatus_set
  octeontx: use rte_eth_linkstatus_set
  enic: use _rte_eth_linkstatus_set
