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 Jesse Brandeburg (2): iavf: Fix performance with writeback policy ice: update writeback policy to reduce latency drivers/net/iavf/iavf_ethdev.c | 13 +++++++++++-- drivers/net/ice/ice_ethdev.c | 2 +- 2 files changed, 12 insertions(+), 3 deletions(-) -- 2.25.4
