Subject: [PATCH v5 bpf-next 7/9] libbpf: add SEC name for xdp programs attached to CPUMAP
Date: Tue, 30 Jun 2020 14:49:42 +0200
Message-ID: <de19593f7e2991bc64f7362054c1a00378a50567.1593521030.git.lorenzo@kernel.org> (raw)
In-Reply-To: <cover.1593521029.git.lorenzo@kernel.org>

As for DEVMAP, support SEC("xdp_cpumap/") as a short cut for loading
the program with type BPF_PROG_TYPE_XDP and expected attach type
BPF_XDP_CPUMAP.
