Subject: [PATCH v1] rdma_rxe: Ensure rdma_rxe init occurs at correct time
Date: Fri, 23 Sep 2016 09:32:11 -0600 [thread overview]
Message-ID: <1474644731-27818-1-git-send-email-sbates@raithlin.com> (raw)
This patch is based off v4.8-rc6 with the recent rxe bugfix patchset
applied [1].
There is a problem when CONFIG_RDMA_RXE=y and CONFIG_IPV6=y. This
results in the rdma_rxe initialization occurring before the IPv6
services are ready. This patch delays the initialization of rdma_rxe
until after the IPv6 services are ready. This fix is based on one
proposed by Logan Gunthorpe on a much older code base [2].
