manually generated abf FibPath gives error? #1092

@ondrej-fabry i have generated the abf.ba.go file and it have this struct:

type FibPath struct { SwIfIndex uint32 TableID uint32 Weight uint8 Preference uint8 IsLocal uint8 IsDrop uint8 IsUDPEncap uint8 IsUnreach uint8 IsProhibit uint8 IsResolveHost uint8 IsResolveAttached uint8 IsDvr uint8 IsSourceLookup uint8 Afi uint8 NextHop []byte struc:"[16]byte" NextHopID uint32 RpfID uint32 ViaLabel uint32 NLabels uint8 LabelStack []FibMplsLabel struc:"[16]FibMplsLabel"

}
the label stack field gives this error: error struc: field LabelStack is a slice with no length or sizeof field is this is the solution here

Yes, correct.

You need to apply the patches we have in binapi folder.

We do the patch apply here: https://github.com/ligato/vpp-agent/blob/1d8fb8efaed02c622054e2a13648b736e7225950/Makefile#L147

This is due some inconsistency in the VPP binary API that defines fixed size array ([16]FibMplsLabel) together with field (NLabels), which defines variable size of that array.
