The first patch adds a new extra type to enable proper synchronization between an RX request/response pair. The second patch implements BFP interface for xen-netfront. The third patch enables extra space for XDP processing.
v13: - fixed compilation due to previous rename v12: - xen-netback: rename netfront_xdp_headroom to xdp_headroom v11: - add the new headroom constant to netif.h - xenbus_scanf check - lock a bulk of puckets in xennet_xdp_xmit() v10: - add a new xen_netif_extra_info type to enable proper synchronization between an RX request/response pair. - order local variable declarations v9: - assign an xdp program before switching to Reconfiguring - minor cleanups - address checkpatch issues v8: - add PAGE_POOL config dependency - keep the state of XDP processing in netfront_xdp_enabled - fixed allocator type in xdp_rxq_info_reg_mem_model() - minor cleanups in xen-netback v7: - use page_pool_dev_alloc_pages() on page allocation - remove the leftover break statement from netback_changed v6: - added the missing SOB line - fixed subject v5: - split netfront/netback changes - added a sync point between backend/frontend on switching to XDP - added pagepool API v4: - added verbose patch descriprion - don't expose the XDP headroom offset to the domU guest - add a modparam to netback to toggle XDP offset - don't process jumbo frames for now v3: - added XDP_TX support (tested with xdping echoserver) - added XDP_REDIRECT support (tested with modified xdp_redirect_kern) - moved xdp negotiation to xen-netback v2: - avoid data copying while passing to XDP - tell xen-netback that we need the headroom space Denis Kirjanov (3): xen: netif.h: add a new extra type for XDP xen networking: add basic XDP support for xen-netfront xen networking: add XDP offset adjustment to xen-netback drivers/net/Kconfig | 1 + drivers/net/xen-netback/common.h | 4 + drivers/net/xen-netback/interface.c | 2 + drivers/net/xen-netback/netback.c | 7 + drivers/net/xen-netback/rx.c | 15 +- drivers/net/xen-netback/xenbus.c | 34 ++++ drivers/net/xen-netfront.c | 337 ++++++++++++++++++++++++++++++++++-- include/xen/interface/io/netif.h | 20 ++- 8 files changed, 408 insertions(+), 12 deletions(-) -- 1.8.3.1
