OK, well understood the requirement for such flags. Thanks for your replies.
I think that for simplicity I will add two more flags on the Tx offloads
capabilities:
DEV_TX_OFFLOADS _MULTI_MEMPOOL <** Device supports transmission of mbufs from
multiple mempools. */
DEV_TX_OFFLOADS_INDIRECT_MBUFS <** Device support transmission of indirect
mbufs. */
Indirect mbufs is just an example when reference counters are required.
Direct mbufs may use reference counters as well.
Those caps can be reported by the PMD as per-port/per-queue offloads.
Application will choose how to set those. When not set - PMD can assume all
mbufs has ref_cnt = 1 and the same mempool.
Any objection?
