Subject: [RFC bpf-next 0/8] xdp: introduce xdp-feature support
Date: Mon, 19 Dec 2022 16:41:29 +0100 [thread overview]
Message-ID: <cover.1671462950.git.lorenzo@kernel.org> (raw)
Introduce the capability to export the XDP features supported by the NIC.
Introduce a XDP compliance test tool (xdp_features) to check the features
exported by the NIC match the real features supported by the driver.
Allow XDP_REDIRECT of non-linear XDP frames into a devmap.
Export XDP features for each XDP capable driver.
Kumar Kartikeya Dwivedi (1):
libbpf: add API to get XDP/XSK supported features
Lorenzo Bianconi (3):
tools: uapi: align if_link.h
bpf: devmap: check XDP features in bpf_map_update_elem and
__xdp_enqueue
selftests/bpf: introduce XDP compliance test tool
Marek Majtyka (4):
net: introduce XDP features flag
drivers: net: turn on XDP features
xsk: add usage of XDP features flags
xsk: add check for full support of XDP in bind
