Hi,

We are facing an issue at the Transmit side randomly = after 8 to 10 days of network traffic flow on the Intel X710 10G NIC with i= 40e PMD.
We found the issue is at Transmit side Tx-queue, as the Tx pac= kets were not going out and also observed that the Tx-queue stats were not = incrementing, even though we are sending packets out through the 'rte_e= th_tx_burst()', this function returns '0'. Whereas the Rx-packe= ts were received well at the same-time and Rx-stats were incremented well, = even the NIC Link is also stable at 1G speed.

So, has anyone faced= such issue on this DPDK i40e PMD at Transmit side(Tx-queue), if so, please= let us know, if any known-issue 'Or' fix/work-around on this.
=
DPDK-version: DPDK-21.11
X710 NIC speed: Connected with 1G speed s= witch-port. so, as per auto-negotiation the link-speed is 1G only.
X710= NIC firmware-version: "fw 6.0.48442 api 1.7 nvm 6.01 0x80003b43 1.182= 4.0 [8086:1589] [108e:7b1c]".

Thanks,
Madhukar.
