Subject: [dpdk-dev] how to control receive timer for the wthresh?
Date: Sun, 27 Jul 2014 13:00:22 +0300	[thread overview]
Message-ID: <CAF8yGaGDPTCzYq=196NaYf4zfDC_n4D198OkKM+vYbZ6z0BHhg@mail.gmail.com> (raw)

Hi all,

Is there, on dpdk 1.6, an API for controlling the receive timer (EITR)
expiration of the wthresh on the NICs?
when setting, for example, .wthresh to 4 and transmitting 7 packets to the
application, then the last 3 packets remains in the on-chip-buffer for too
long and are written to the host memory only after few seconds, which is
not acceptable (in my case using 82575).

is there a way to config this?

Thanks
Sim
