different sl 2 vl mapping for switch ports
connected to HCAs.

Should be CAs as this includes TCAs too, right ?
Should router peer ports also be included here ?

IMO QoS docs and opensm man page should also be updated to go along with this.

How does this work when optimized SL to VL programming is enabled and
supported on the device ? Doesn't some handling need to be added for
this ?

Are edge ports the same as leaf ports ? If so, it would be better to
use that terminology if it is the same as it is already used and
exposed in OpenSM. Maybe the difference is that edge ports currently
appear to only have CA ports as peers whereas leaf ports have CA or
router ports as peers.
