Subject: [dpdk-dev] [PATCH v2 0/2] intel: fix writeback
Date: Fri, 23 Oct 2020 13:21:58 -0700
Message-ID: <20201023202200.1909832-1-jesse.brandeburg@intel.com> (raw)

This patch series is targeted at the v20.11 release.

It fixes two separate bugs, on the PF with reducing the latency
from 16us to 2us maximum for a single packet, and on the VF with
adding an ITR timeout to both allow descriptor aggregation for
writeback, and minimize latency, setting the value to the same as
the PF for E810 family.

v2: subscribe to list and re-send

  ice: update writeback policy to reduce latency
