The commitc69de58ba8("net: erspan: use bitfield instead of mask and offset") changes the erspan header to use bitfield, and commitd350a82302("net: erspan: create erspan metadata uapi header") creates a uapi header file. The above two commit breaks the current erspan test. This patch fixes it by adapting the above two changes. Fixes:ac80c2a165("samples/bpf: add erspan v2 sample code") Fixes:ef88f89c83("samples/bpf: extend test_tunnel_bpf.sh with ERSPAN") Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: David S.
