This change has following ABI breakage[1].

Could you move ca_enqueue at end of struct to avoid the ABI breakage. Also, please update depreciation notice to move ca_enqueue to above(to align with function pointers) in 21.11 release.

[1]
  [C]'function rte_eventdev* rte_event_pmd_allocate(const char*, int)' at rte_eventdev.c:1467:1 has some indirect sub-type changes:
    return type changed:
      in pointed to type 'struct rte_eventdev' at rte_eventdev.h:1411:1:
        type size hasn't changed
        1 data member insertion:
          'event_crypto_adapter_enqueue rte_eventdev::ca_enqueue', at offset 512 (in bits) at rte_eventdev.h:1430:1
        5 data member changes:
         'rte_eventdev_data* rte_eventdev::data' offset changed from 512 to 576 (in bits) (by +64 bits)
         'rte_eventdev_ops* rte_eventdev::dev_ops' offset changed from 576 to 640 (in bits) (by +64 bits)
         'rte_device* rte_eventdev::dev' offset changed from 640 to 704 (in bits) (by +64 bits)
         'uint64_t rte_eventdev::reserved_64s[4]' offset changed from 768 to 832 (in bits) (by +64 bits)
         type of 'void* rte_eventdev::reserved_ptrs[4]' changed:
           type name changed from 'void*[4]' to 'void*[3]'
           array type size changed from 256 to 192
           array type subrange 1 changed length from 4 to 3
         and offset changed from 1024 to 1088 (in bits) (by +64 bits)
