To elaborate more...
Assuming an example of vmxnet3 driver, at present, when rte_eth_tx_burst() is
called to send mbufs, vmxnet3 driver calls vmxnet3_tq_tx_complete() to free up
completed buffers. Instead, wondering, if vmxnet3 (or corresponding driver)
can trigger application callback for the buffer (mbuf) which gets transmitted
out of n/w interface. Application callback can decide now decide whether to
reuse the mbuf and continue multicasting on other tunnels.
Thanks,

Subject: [dpdk-dev] Callbacks after buffer (mbuf) sent out
Hi,
I am looking for application callbacks after mbufs are sent (tx) out
successfully. One of the use cases is for async multicast (over different gre
tunnels etc). Using direct/indirect buffers along with ref-count itself is
not enough, as actual 'pkt-data' itself changes while flooding on list of
tunnels.
Thanks,
-Vithal
