Merge branch 'mvneta-xdp'
Lorenzo Bianconi says:
====================
add XDP support to mvneta driver
Add XDP support to mvneta driver for devices that rely on software
buffer management. Supported verdicts are:
- XDP_DROP
- XDP_PASS
- XDP_REDIRECT
- XDP_TX
Moreover set ndo_xdp_xmit net_device_ops function pointer in order
to support redirecting from other device (e.g. virtio-net).
Convert mvneta driver to page_pool API.
This series is based on previous work done by Jesper and Ilias.
We will send follow-up patches to reduce DMA-sync operations.
Changes since v4:
- reset page_pool pointer to NULL in mvneta_rxq_drop_pkts and in
mvneta_create_page_pool error path
- move dma sync in mvneta_rx_refill() in patch 2/7
- verify bpf prog pointer in mvneta_xdp_setup to double-check if
stop/start is really necessary
- coding style fixes
Changes since v3:
- rename MVNETA_XDP_CONSUMED in MVNETA_XDP_DROPPED
- squash patch 4/8 and patch 3/8
- fix dma sync for XDP_TX verdict
- fix queue_index in xdp_rxq_info_reg
- cosmetics
Changes since v2:
- rely on page_pool_recycle_direct instead of xdp_return_buff for XDP_DROP
- define xdp buffer in mvneta_rx_swbm and avoid default initializations
- use dma_sync_single_for_cpu instead of dma_sync_single_range_for_cpu
- run page_pool_release_page in mvneta_swbm_add_rx_fragment even if
the buffer contains just ETH_FCS
Changes since v1:
- sync dma buffers before refilling hw queues
- fix stats accounting
Changes since RFC:
- implement XDP_TX
- make tx pending buffer list agnostic
- code refactoring
- check if device is running in mvneta_xdp_setup
