[openib-general] Re: [PATCH][kdapl] Integrate dapl_hca_alloc/dapl_hca_free to dapl_provider.c

For consistency, I think we should keep the HCA object in its own 
file. 

However, I'm not sure we need an HCA object. Is there a better way to 
organize the data being stored in the dapl_hca structure? I have this 
feeling that we should merge all the structures that we create on a 
per-hca basis (the dapl_provider_entry, dat_provider table, and 
dapl_hca).
