netlink: specs: rt-link: convert bridge port flag attributes to u8

2026-07-21T01:14:42Z

A number of IFLA_BRPORT_* attributes are documented in the rt-link spec as having the "flag" type, i.e. a payload-less NLA_FLAG attribute whose meaning is presence-only. This does not match the kernel, which emits these attributes with nla_put_u8() and validates them as NLA_U8 in br_port_policy[]. The values are not mere presence flags but carry a u8 payload (0/1). Convert these bridge port attributes from "flag" to "u8" so the spec reflects the actual wire format.
