[dpdk-dev] Callbacks after buffer (mbuf) sent out

2015-01-16 Thread Vithal S Mohare
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,
