MX204 tunnel services BW

[Jeff Behrns via NANOG <nanog () nanog org>]

Encountered an issue with an MX204 using all 4x100G ports and a logical
tunnel to hairpin a VRF.  The tunnel started dropping packets around 8Gbps.
I bumped up tunnel-services BW from 10G to 100G which made the problem
worse; the tunnel was now limited to around 1.3Gbps.  To my knowledge with
Trio PFE you shouldn't have to disable a physical port to allocate bandwidth
for tunnel-services.  Any helpful info is appreciated.
