Public bug reported:
SRU Justification:
Impact: in order to properly support infiniband for Azure A8/A9,
H-series, and NC24/NV24 instances, multiple versions of the driver must
be maintained and userspace must be responsible for selecting the
correct version of the driver.
That's already supported in the linux-azure kernel with the userspace
logic implemented in the Windows Azure Linux Agent. The Xenial kernel is
carrying a single version of the RDMA which might cause problems if the
host OS requires a different version of the driver.
Fix: remove the driver located at "drivers/infiniband/hw/vmbus-rdma/"
from the Xenial kernel and keep support to it only in linux-azure.
Testcase: the module "hv_network_direct.ko" should not be include in the
linux-image or linux-image-extra packages.
