Subject: [PATCH] rdma_rxe: Ensure rdma_rxe module init occurs at correct time
Date: Thu, 15 Sep 2016 15:45:36 -0600	[thread overview]
Message-ID: <1473975936-9970-1-git-send-email-sbates@raithlin.com> (raw)

When the Soft-RoCE module is built into the kernel there is a
initialization issue when CONFIG_IPV6 is selected. Use late_initcall
to ensure the rxe module is loaded later. This fix is based on one
proposed by Logan Gunthorpe on a much older code base [1].
