From: Intel-wired-lan <intel-wired-lan-bounces@xxxxxxxxxx> On Behalf Of Maciej Fijalkowski Sent: Monday, January 18, 2021 7:13 AM To: intel-wired-lan@xxxxxxxxxxxxxxxx Cc: netdev@xxxxxxxxxxxxxxx; kuba@xxxxxxxxxx; bpf@xxxxxxxxxxxxxxx; Topel, Bjorn <bjorn.topel@xxxxxxxxx>; Karlsson, Magnus <magnus.karlsson@xxxxxxxxx> Subject: [Intel-wired-lan] [PATCH v3 net-next 10/11] ice: store the result of ice_rx_offset() onto ice_ring Output of ice_rx_offset() is based on ethtool's priv flag setting, which when changed, causes PF reset (disables napi, frees irqs, loads different Rx mem model, etc.). This means that within napi its result is constant and there is no reason to call it per each processed frame. Add new 'rx_offset' field to ice_ring that is meant to hold the ice_rx_offset() result and use it within ice_clean_rx_irq(). Furthermore, use it within ice_alloc_mapped_page().
