While writing hyper-v 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.
v8
- fix typo in 32bit exchange
- fix build of dpaa2
- go back to same return value as original code
- reduce number of lines changed
v7
- add exchange functions for PPC64
- move linkstatus helpers to rte_ethdev_driver
- rebase to 18.02
