Just saw this patch set this morning. Few comments:

1. I think nla_bitfield or nla_bitmap is a better name than nla_flag_bits

2. The length should be open ended with the size of the array determined
by nla_len / sizeof(struct nla_bitfield). That allows this to be
extended to an arbitrary large bitfield as needed.

3. IMO since these are nla prefixes and new NLA type they should be in
uapi/linux/netlink.h
