Hi Hal,
This small patch fixes two similar bugs in Up/Dn routing in OpenSM.
A 8-bits integers were used as indexes when scanning subnet, which
in one case caused OpenSM to crash when ranking "path" is longer
than 256 switches, and in other case caused OpenSM to go into infinite
loop when fabric has more than 256 roots.
Please apply both to ofed_1_2 and to master.
