In ib_srp.c sg_tablesize is defined as 255. With that value we see lots of IO requests of size 1020. As I already wrote on linux-scsi, that is really sub- optimal for DDN storage, as lots of IO requests of size 1020 come up.
Now the question is if we can safely increase it. Is there somewhere a definition what is the real hardware supported size? And shouldn't we increase sg_tablesize, but also set the .dma_boundary value?
