From 6c5e683925cf19d36033f3e9e9d90755f034614e Mon Sep 17 00:00:00 2001 From: Bob Pearson Date: Tue, 13 Sep 2022 17:27:17 -0500 Subject: RDMA/rxe: Remove redundant num_sge fields In include/uapi/rdma/rdma_user_rxe.h there are redundant copies of num_sge in the rxe_send_wr, rxe_recv_wqe, and rxe_dma_info. Only the ones in rxe_dma_info are actually used by the rxe kernel driver. The userspace would set these values, but the kernel never read them. This change has no affect on the current ABI and new or old versions of rdma-core operate correctly with new or old versions of the kernel rxe driver.
