This series introduces a new tracepoint in bpf_xdp_link_attach(). By this tracepoint, error message will be captured when error happens in dev_xdp_attach(), e.g. invalid attaching flags.
v4 -> v5: * Initialise the extack variable. * Fix code style issue of variable declaration lines.
v3 -> v4: * Fix selftest-crashed issue.
