Dumping SL, MTU and Rate for all the
non-switch-2-non-switch paths in the subnet.
PRs that are dumped:
for every non-switch source port
for every non-switch target LID in the subnet
dump PR between source port and target LID
This way number of sources is equal to number of physical
non-switch ports in the subnet, and only number of targets
depends on LMC that is used.

Otherwise we stop dumping at the first switch we encounter?
