In Sec. 14.1, current transport draft said that:
"Each pair of local and remote addresses could have a different PMTU. QUIC implementations that implement any kind of PMTU discovery therefore SHOULD maintain a maximum packet size for each combination of local and remote IP addresses."

However, if only UDP port changes, ECMP could cause traffic to be routed through different physical paths, which potentially have different PMTUs. I wonder if Maximum packet size should be per 4-tuple instead.
