Hi Or,
All 32 CQs will never get used. Here are the reasons:
1) current #define ISER_MAX_CQ 4
2) Your proposed TODO "#1. change the number of CQs to be min(num_cpus, 1/2 of
what the device can support)"
This would limits the max CQs device supports to 1/2 anyway.
If you don't agree, I like to get your suggestions of what I should do in this
case for CQs that have 8k of entries each.
Thanks.
