  To: dev; +Cc: Ray Kinsella

The mbuf offload flags do not match the DPDK namespace (they are
not prefixed by RTE_). Announce their rename in 21.11, and the
removal of the old names in 22.11.

A draft coccinelle script is provided to anticipate what the
renaming will be.

+// Rename mbuf offload flags (and some other defines) to have
+// an RTE_ prefix.
+// This only replaces usages in C code, so it is advised to
+// check for missing occurences with:
+//   for f in $(git ls-tree --full-tree -r --name-only HEAD); do
+//     if [ "$(file -b --mime-encoding $f)" != binary ]; then
+//       sed -i -e 's,PKT_RX_,RTE_MBUF_F_RX_,g' \
+//         -e 's,PKT_TX_,RTE_MBUF_F_TX_,g' \
+//         -e 's,EXT_ATTACHED_MBUF,RTE_MBUF_F_EXTERNAL,g' \
+//         -e 's,IND_ATTACHED_MBUF,RTE_MBUF_F_INDIRECT,g' \
+//         -e 's,PKT_FIRST_FREE,RTE_MBUF_F_FIRST_FREE,g' \
+//         -e 's,PKT_LAST_FREE,RTE_MBUF_F_LAST_FREE,g' $f

 * cmdline: ``cmdline`` structure will be made opaque to hide platform-specific
