The patches of TAP RSS eBPF follow the RFC on this issue https://dpdk.org/dev/patchwork/patch/31781/
Pascal Mazon (1): net/tap: add BPF sections for TAP device ======================================== This commit introduces BPF program (tap_bpf_program.c) with different sections which should be loaded to the kernel in BPF architecture format. BPF code compilation is not part of dpdk compilation. This commit also adds a skeleton for the RAP RSS implementation Ophir Munk (2): net/tap: add eBPF instructions ============================== This commit adds eBPF machine instructions as part of dkdk compilation in the format of C arrays. This approach is currently under review with regard to: - licensing - Ability to update a BPF program and download new machine code net/tap: add eBPF classifiers map and actions ============================================= This commit builds and sends netlink messages to the kernel that include BPF classifiers and actions. When using BPF system call to load code to the kernel a license name must be specified. The license name is currently set to "Dual BSD/GPL". Please note licensing in general is under review and is not adderessed in this patch. doc/guides/prog_guide/rte_flow_tap.rst | 962 ++++++ drivers/net/tap/Makefile | 7 +- drivers/net/tap/rte_eth_tap.h | 9 +- drivers/net/tap/tap_bpf_insns.c | 5460 ++++++++++++++++++++++++++++++++ drivers/net/tap/tap_bpf_program.c | 321 ++ drivers/net/tap/tap_bpf_shared.h | 56 + drivers/net/tap/tap_flow.c | 613 +++- 7 files changed, 7323 insertions(+), 105 deletions(-) create mode 100644 doc/guides/prog_guide/rte_flow_tap.rst create mode 100644 drivers/net/tap/tap_bpf_insns.c create mode 100644 drivers/net/tap/tap_bpf_program.c create mode 100644 drivers/net/tap/tap_bpf_shared.h -- 2.7.4
