[Openib-windows] CA capabilities

[Yossi Leybovich]

Fab

Simple test that try to allocate max PDs (as reported form query ca)
discovered that 
it can allocate only the max_pds -1.
I checked it and found that:

The user ask for 0x4000 PDs
The THH layer keep 2 PDs for itself so the IBAL report on 0x3ffe PDs
available
while the IBAL is loaded (in creat_ci_ca) IBAL take one more PD (for SQP..)
so the user can allocate only 0x3ffd PDs
Do you think that IBAL should report 1 PD less so the user will know exactly
how many resources he actually can allocate ?

Personally I think that if IBAL take resource (PDs, Avs, QPS) for its own
use,
then it should subtract them from the ca capabilities.

What do you think ?
