Hi,

I hope you are well.

During the traffic test, TX adapter showed starvation due to Rx adapter processing on the same dpdk-core 03 and dropped the 41412 packets after 154655 tx_retry.
So, I expect I have to assign TX/RX adapter on each dpdk-core to prevent starvation and packet drop.

Are those tx_retry and tx_dropped packet due to RX adapter packet processing?
Is it possible to separate TX/RX adapter into different dpdk-core?
