On digging further found some more data.
On the host where everything works fine, I can see 'txq->nb_tx_free' getting
reduced to 31 from 1024. After reaching at 31, i40e_tx_free_bufs() function
gets called, which frees the buffer and nb_tx_free reaches to 63.
Also in the function i40e_tx_free_b
I doubled the mempool size to 65535 but the issue is not resolved.

Hi Stephen,
Thanks for the reply.
Our mbuf pool is big enough. We have 2 RX cores, 2 TX cores and 8 worker cores.
NTxd and NRxd is 1024 each and we have 16 Rx rings (shared between Rx and
workers) and 8 Tx rings (between Tx and workers)
Mempool cache size is 256 and burst size is 32.
So overall

Hi All,
We are trying to debug and fix an issue. After the deployment, in few of the
hosts we see an issue where TX is unable to enqueue packets to NIC. On
rebouncing or restarting our packet processor daemon, issue gets resolved.
We are using IntelDPDK version 17.11.4 and i40e drivers.
