Subject: [dpdk-users] TX/RX adapter running on the same core problem
Date: Sun, 26 Sep 2021 05:21:39 +0000 [thread overview]
Message-ID: <HE1PR07MB422001F687F7DBA040C062E5F3A69@HE1PR07MB4220.eurprd07.prod.outlook.com> (raw)
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?
