RDMA/cxgb4: "cookie" can stay in host endianness
Work requests are passed between the host and the firmware with a
"cookie". This cookie is swapped to big-endian when passed to the
firmware and back to host endianness on return. This swapping seems
to be implemented incorrectly. Moreover, the byte swapping triggers
GCC warnings on 32 bit:
drivers/infiniband/hw/cxgb4/cm.c: In function ‘passive_ofld_conn_reply’:
drivers/infiniband/hw/cxgb4/cm.c:2803:12: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
drivers/infiniband/hw/cxgb4/cm.c: In function ‘send_fw_pass_open_req’:
drivers/infiniband/hw/cxgb4/cm.c:2941:16: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
[...]
But byte swapping isn't needed as the firmware doesn't actually touch
the cookie. Dropping byte swapping makes the warnings go away too.
