Hey Arlin,
We've uncovered a problem with the DAPL attribute mappings to the linux
rdma device attributes.
The DAPL dat_ia_attr->max_lmr_block_size is a u32, yet the dapl code
maps this to the linux ib_device_attr->max_mr_size which is u64.
This causes dapltest to fail in some cases when running over chelsio
which sets max_mr_size to 0x100000000 (4GB). The dapl code truncates
the value to 0. See dapl/openib_cma/dapl_ib_util.c.
I'm not sure what the fix should be, but maybe the dapl code should set
anything over 32 bits to 0xffffffff?
Steve.
