mpr driver does not show all paths to dual-port disks.
Tested on 2 LSI 9300-8e connected to HP D2700 （SAS2) disk external enclosure with 12 HDDs on HP DL360p Gen9 and HP D3700 (SAS3) disk enclosure with 10 SSDs and Supermicro X10SRH-CLN4F, FreeBSD 12.1 and 12.2
Same hardware setup works perfectly on Linux.
mps driver (LSI 9207-8e) also works fine in FreeBSD
I attached dmesg.log, geom, mprutil and sesutil output
as you can see from geom output it can see only 1 device with 2 paths
