2019-07-08net: ethernet: ti: cpsw: add XDP supportIvan Khoronzhuk4-59/+488
Add XDP support based on rx page_pool allocator, one frame per page. Page pool allocator is used with assumption that only one rx_handler is running simultaneously. DMA map/unmap is reused from page pool despite there is no need to map whole page. Due to specific of cpsw, the same TX/RX handler can be used by 2 network devices, so special fields in buffer are added to identify an interface the frame is destined to. Thus XDP works for both interfaces, that allows to test xdp redirect between two interfaces easily. Also, each rx queue have own page pools, but common for both netdevs. XDP prog is common for all channels till appropriate changes are added in XDP infrastructure. Also, once page_pool recycling becomes part of skb netstack some simplifications can be added, like removing page_pool_release_page() before skb receive. In order to keep rx_dev while redirect, that can be somehow used in future, do flush in rx_handler, that allows to keep rx dev the same while redirect. It allows to conform with tracing rx_dev pointed by Jesper. Also, there is probability, that XDP generic code can be extended to support multi ndev drivers like this one, using same rx queue for several ndevs, based on switchdev for instance or else. In this case, driver can be modified like exposed here: https://lkml.org/lkml/2019/7/3/243 Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S.

2019-07-08net: core: page_pool: add user refcnt and reintroduce page_pool_destroyIvan Khoronzhuk2-8/+4
Jesper recently removed page_pool_destroy() (from driver invocation) and moved shutdown and free of page_pool into xdp_rxq_info_unreg(), in-order to handle in-flight packets/pages. This created an asymmetry in drivers create/destroy pairs. This patch reintroduce page_pool_destroy and add page_pool user refcnt. This serves the purpose to simplify drivers error handling as driver now drivers always calls page_pool_destroy() and don't need to track if xdp_rxq_info_reg_mem_model() was unsuccessful. This could be used for a special cases where a single RX-queue (with a single page_pool) provides packets for two net_device'es, and thus needs to register the same page_pool twice with two xdp_rxq_info structures. This patch is primarily to ease API usage for drivers. The recently merged netsec driver, actually have a bug in this area, which is solved by this API change. This patch is a modified version of Ivan Khoronzhuk's original patch.

On unusual page sizes, we get harmless warnings: drivers/net/ethernet/google/gve/gve_rx.c:283:6: error: unused variable 'pagecount' [-Werror,-Wunused-variable] drivers/net/ethernet/google/gve/gve_rx.c:336:1: error: unused label 'have_skb' [-Werror,-Wunused-label] Change the preprocessor #if to regular if() to avoid this.

2019-07-08net: stmmac: Re-work the queue selection for TSO packetsJose Abreu1-10/+18
Ben Hutchings says: "This is the wrong place to change the queue mapping. stmmac_xmit() is called with a specific TX queue locked, and accessing a different TX queue results in a data race for all of that queue's state. I think this commit should be reverted upstream and in all stable branches. Instead, the driver should implement the ndo_select_queue operation and override the queue mapping there."

2019-07-05net/mlx5e: Add kTLS TX HW offload supportTariq Toukan14-7/+748
Add support for transmit side kernel-TLS acceleration. Offload the crypto encryption to HW. Per TLS connection: - Use a separate TIS to maintain the HW context. - Use a separate encryption key. - Maintain static and progress HW contexts by posting the proper WQEs at creation time, or upon resync. - Use a special DUMP opcode to replay the previous frags and sync the HW context. To make sure the SQ is able to serve an xmit request, increase SQ stop room to cover: - static params WQE, - progress params WQE, and - resync DUMP per frag. Currently supporting TLS 1.2, and key size 128bit. Tested over SimX simulator.
