From: Honggang LI <honggangli@xxxxxxx>
commit 03fa18a992d5626fd7bf3557a52e826bf8b326b3 upstream.
For RDMA Send and Write with IB_SEND_INLINE, the memory buffers
specified in sge list will be placed inline in the Send Request.
The data should be copied by CPU from the virtual addresses of
corresponding sge list DMA addresses.
