From b846f25aa2a353355aec5202fe4dbdc6674dfc64 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Wed, 16 Apr 2008 21:09:27 -0700 Subject: IB/core: Add creation flags to struct ib_qp_init_attr Add a create_flags member to struct ib_qp_init_attr that will allow a kernel verbs consumer to create a pass special flags when creating a QP. Add a flag value for telling low-level drivers that a QP will be used for IPoIB UD LSO. The create_flags member will also be useful for XRC and ehca low-latency QP support. Since no create_flags handling is implemented yet, add code to all low-level drivers to return -EINVAL if create_flags is non-zero.
