Hey Folks, I'm running into an issue that I hope is obvious and simple. We're running DPDK 1.6.2 with an 82599 NIC. We find that if, while running traffic, we disconnect a port and then later reconnect it, we never regain the ability to transmit packets out of that port after it comes back up. Specifically, our calls to rte_eth_tx_burst() get return values that indicate that no packets could be sent.
Is there an additional step that we have to do on link down/up operations, perhaps to tell the NIC to flush its descriptor ring? Thanks in advance for your help. -- Matt Laswell *infinite io, inc.* laswell at infiniteio.com
