We started generating C code for OvS a while back, but actually
C codegen only supports fixed headers specified at the family
level right now (schema also allows specifying them per op).
ovs_flow and ovs_datapath already specify the fixed header
at the family level but ovs_vport does it per op.
Move the property, all ops use the same header.
This ensures YNL C sees the correct hdr_len:
const struct ynl_family ynl_ovs_vport_family = {
.name = "ovs_vport",
- .hdr_len = sizeof(struct genlmsghdr),
+ .hdr_len = sizeof(struct genlmsghdr) + sizeof(struct ovs_header),
};
Fixes: 7c59c9c8f2 ("tools: ynl: generate code for ovs families")
