From 3f44675439b136d51179d31eb5a498383cb38624 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 4 Aug 2008 11:02:14 -0700 Subject: RDMA/cma: Remove padding arrays by using struct sockaddr_storage There are a few places where the RDMA CM code handles IPv6 by doing struct sockaddr addr; u8 pad[sizeof(struct sockaddr_in6) - sizeof(struct sockaddr)]; This is fragile and ugly; handle this in a better way with just struct sockaddr_storage addr; [ Also roll in patch from Aleksey Senin to switch to struct sockaddr_storage and get rid of padding arrays in struct rdma_addr. ] Signed-off-by: Roland Dreier --- include/rdma/rdma_cm.h | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) (limited to 'include') diff --git a/include/rdma/rdma_cm.h b/include/rdma/rdma_cm.h index df7faf09d66..c6b2962315b 100644 --- a/include/rdma/rdma_cm.h +++ b/include/rdma/rdma_cm.h @@ -71,12 +71,8 @@ enum rdma_port_space { }; struct rdma_addr { - struct sockaddr src_addr; - u8 src_pad[sizeof(struct sockaddr_in6) - - sizeof(struct sockaddr)]; - struct sockaddr dst_addr; - u8 dst_pad[sizeof(struct sockaddr_in6) - - sizeof(struct sockaddr)]; + struct sockaddr_storage src_addr; + struct sockaddr_storage dst_addr; struct rdma_dev_addr dev_addr; }; -- cgit v1.2.3 From f780a9f119caa48088b230836a7fa73d1096de7c Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Wed, 6 Aug 2008 20:14:06 -0700 Subject: mlx4_core: Add ethernet fields to CQE struct Add ethernet-related fields to struct mlx4_cqe so that the mlx4_en ethernet NIC driver can share the same definition.
