This patch introduces the RoCE driver for the Broadcom NetXtreme-E 10/25/40/50G RoCE HCAs. The RoCE driver is a two part driver that relies on the parent bnxt_en NIC driver to operate. The changes needed in the bnxt_en driver have already been incorporated via Dave Miller's net tree into the mainline kernel. The vendor official git repository for this driver is available on github as: https://github.com/Broadcom/linux-rdma-nxt/ Signed-off-by: Eddie Wai <eddie.wai@broadcom.com> Signed-off-by: Devesh Sharma <devesh.sharma@broadcom.com> Signed-off-by: Somnath Kotur <somnath.kotur@broadcom.com> Signed-off-by: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> Signed-off-by: Selvin Xavier <selvin.xavier@broadcom.com> Reviewed-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
