I just tried to upgrade to 2.1.0 and suddenly my code stopped compiling,
because of using PKT_RX_IPV4_HDR feature flag and the like. In the
rte_mbuf.h there is this code:

quoted

#ifndef RTE_NEXT_ABI
#define PKT_RX_IPV4_HDR      (1ULL << 5)  /**< RX packet with IPv4 header. */
#define PKT_RX_IPV4_HDR_EXT  (1ULL << 6)  /**< RX packet with extended IPv4 header. */
#define PKT_RX_IPV6_HDR      (1ULL << 7)  /**< RX packet with IPv6 header. */
#define PKT_RX_IPV6_HDR_EXT  (1ULL << 8)  /**< RX packet with extended IPv6 header. */
#endif /* RTE_NEXT_ABI */

In order to keep compatibility with your old code, you have to disable
RTE_NEXT_ABI in your configuration file (.config).

So I guess that means the code got deprecated between 2.0.0 and 2.1.0,
although I did not find relevant comment in the changelog. My question
is, what should I use instead and even better - why was this change made?
