[PATCH v3 bpf-next 1/5] devmap: Formalize map value as a named struct

Add 'struct bpf_devmap_val' to the bpf uapi to formalize the expected values that can be passed in for a DEVMAP. Update devmap code to use the struct. Signed-off-by: David Ahern --- include/uapi/linux/bpf.h | 5 + kernel/bpf/devmap.c| 40 +++---
