Since we're bumping the ABI/API, does anyone see any issues with changing the
layout of ib_send_wr? It would end up being terribly convenient if you could
cast between the OFED ib_send_wr and WinOF ib_send_wr, especially since the HW
drivers and libraries are derived from the OFED stack. This avoids translating
structures in the speed path.
For example, change from:
typedef struct _ib_send_wr
{
TO_LONG_PTR(struct _ib_send_wr* , p_next) ;
uint64_t wr_id;
ib_wr_type_t wr_type;
ib_send_opt_t send_opt;
uint32_t num_ds;
TO_LONG_PTR(ib_local_ds_t* , ds_array) ;
ib_net32_t immediate_data;
...
to
typedef struct _ib_send_wr
{
uint64_t wr_id;
struct _ib_send_wr* *p_next;
ib_local_ds_t *ds_array;
uint32_t num_ds;
ib_wr_type_t wr_type;
ib_send_opt_t send_opt;
ib_net32_t immediate_data;
...
The field names remain the same. ULPs only need to recompile. If no one
disagrees, I will do this after the latest set of patches hit the trunk.
