Subject: [dpdk-dev] igb PMD should set the default tx wthresh correctly.
Date: Thu, 16 Jul 2015 10:16:50 -0700 [thread overview]
Message-ID: <20150716101650.45c0e25a@urahara> (raw)
Why doesn't igb driver set the wthresh it wants as default?
I see:
PMD: eth_igb_tx_queue_setup(): To improve 1G driver performance, consider setting the TX WTHRESH value to 4, 8, or 16.
But the default tx_conf has wthresh of 0.
#define IGB_DEFAULT_TX_WTHRESH 0
Either message should be removed or default TX wthresh should change.
