[ofa-general] eHCA issues

[Anton Blanchard]

Hi,

Ive been trying to get the DAPL tests running on eHCA. One issue was
traced back to a negative value in ->max_cqe. Looking at all the device
attributes max_pd and max_ah are negative too.

        props->max_cqe         = min_t(int, rblock->max_cqe, INT_MAX);

Can this really be negative or should we be doing:

        props->max_cqe         = min_t(unsigned int, rblock->max_cqe, INT_MAX);

Anton
