From: Ioana Ciornei <ioana.cior...@nxp.com> DMA unmapping, allocating a new buffer and DMA mapping it back on the refill path is really not that efficient. Proper buffer recycling (page pool, flipping the page and using the other half) cannot be done for DPAA2 since it's not a ring based controller but it rather deals with multiple queues which all get their buffers from the same buffer pool on Rx.
To circumvent these limitations, add support for Rx copybreak in dpaa2-eth. Ioana Ciornei (3): dpaa2-eth: rename dpaa2_eth_xdp_release_buf into dpaa2_eth_recycle_buf dpaa2-eth: add rx copybreak support dpaa2-eth: export the rx copybreak value as an ethtool tunable .../net/ethernet/freescale/dpaa2/dpaa2-eth.c | 65 ++++++++++++++----- .../net/ethernet/freescale/dpaa2/dpaa2-eth.h | 10 ++- .../ethernet/freescale/dpaa2/dpaa2-ethtool.c | 40 ++++++++++++ 3 files changed, 97 insertions(+), 18 deletions(-) -- 2.30.0
