Subject: tx_stop_queue and flow control
Date: Tue, 11 Aug 2015 21:11:37 +0000	[thread overview]
Message-ID: <D1EFB318.45AD5%jyu@vmware.com> (raw)

Hello,

DPDK drivers support tx_stop_queue, but they don't use it for flow control, I.e. Stop upper layer calling the device tx_pkt_burst routine when there is no resource. I wonder if flow control is needed here, if yes, is there plan to add this support?

Thanks,
Jia
