To reduce duplication, this patch consolidates them into a common API family and use it for all the PMDs(we started with a few selectively). v9: 1. Change '*addr = (*addr) | mask' to '*addr = val | mask' . 2. Move 'rte_bitops.h' from 'device' section to 'basic' section in 'doxy-api-index.md'. v8: 1. Change 'rte_pmd_bitops.h' to 'rte_bitops.h' allowing for future extension into other cases other than PMD only. 2. Replace '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.
