[dpdk-dev] [PATCH v5 0/6] implement common rte bit operation APIs in PMDs

[Joyce Kong]

There are a lot functions of bit operations scattered in PMDs,
consolidate them into a common API family and applied in different
PMDs to reduce code duplication.

v5:
 Correct the spelling mistake in test_bitops.c

v4:
  Introduce uint32_t/uint64_t *addr when definiting bit operation APIs(suggested by
  Morten Brørup).

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(suggested by Stephen Hemminger).
  2. Add test cases for common rte bit operation API(suggested by Stephen Hemminger).
  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
     (suggested by Jerin Jacob).
  4. Use an well defined uint_NN_t type(suggested by Morten Brørup).

Joyce Kong (6):
  lib/eal: implement the family of rte 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
