MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.
Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.
This change affects the storage size of a variable of enum
rte_ipv6_mc_scope (at least with gcc). It should be OK from an ABI POV
though: there is one (inline) helper using this type, and nothing else
in DPDK takes a IPv6 multicast scope as input.
