Verifying SL2VL tables on QLogic 7300 Series
Adapters
iba_saquery can be used to get the SL2VL mapping for any given port
however, QLogic 7300 series adapters exports the SL2VL mapping via sysfs files.
These files are used by PSM to implement the SL2VL tables automatically. The
SL2VL tables are per port and available under /sys/class/infiniband/hca
name/ports/port #/sl2vl. The directory contains 16 files numbered 0-15
that specify the SL. Listing the SL files returns the VL as programmed by the SL.
