v10:
  Rename the APIs of '_relaxed' suffix to 'rte_bit_relaxed_xx'.
  <Tomas Monjalon>

v9:
  1. Change '*addr = (*addr) | mask' to '*addr = val | mask'.
     <Morten Brørup>
  2. Move 'rte_bitops.h' from 'device' section to 'basic'
     section in 'doxy-api-index.md'. <Jerin Jacob>

v8:
  1. Change 'rte_pmd_bitops.h' to 'rte_bitops.h' allowing for
     future extension into other cases other than PMD only.
  2. Replace omissive 'unsigned long' with 'uint32_t' to fix
     compling errors, the reason is the fact that 32-bit and
     64-bit systems have different sized 'unsigned long', which
     caused incompatibility.

v7:
  1. Change the API's head file to 'rte_pmd_bitops.h' as a common-
     but-not-public file.
  2. Replace C11 atomic operations with 'volatile'. As the use cases
     are limited to PMDs, a 'volatile' is sufficient.

v5,v6:
  Trim 'unsigned long' in PMDs down to 'uint32_t', as on mainstream
  64-bit OS, 'unsigned long' is 64-bit in size, but the 32-bit OS
  expects 32-bit 'unsigned long' argument.

v4:
  Introduce uint32_t/uint64_t *addr when definiting bit operation
  APIs.

v3:
  1. Change the API's head file back to rte_bitops.h, then implement
     both 32-bit and 64-bit operations with and without C11 atomic
     memory ordering.
  2. Add multi-core test case for bit operations which implemented
     with memory ordering.
  3. Modify the doc of both APIs and test cases.

v2:
  1. Add doxygen comments for the rte bit operation API.
  2. Add test cases for common rte bit operation API.
  3. Change the header file to rte_io_bitops.h and the operation to
     rte_io_set_bit() etc., as the API uses barriers inside and the
     barriers are only needed for IO operations.
  4. Use an well defined uint_NN_t type.

Joyce Kong (6):
  lib/eal: implement the family of common bit operation APIs
  test/bitops: add bit operation test case
  net/axgbe: use common rte bit operation APIs instead
  net/bnx2x: use common rte bit operation APIs instead
  net/qede: use common rte bit operation APIs instead
  net/hinic: use common rte bit operation APIs instead
