[ Upstream commit 747fb8413aaa36e4c988d45c4fe20d4c2b0778cd ]
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), };
