"HW issues" -- you need to go into far more detail, when adding a new interface. what hw issues? why was this the best/only solution?



A HW issue requires limiting the receive window size to 23 pages of internal memory. These pages can be configured to different sizes, thus the RDMA driver needs to know the
page size to enforce the upper limit.
