Title:
  Remove vmbus-rdma driver from Xenial kernel

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Xenial:
  In Progress

Bug description:
  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 included in
  the linux-image or linux-image-extra packages.
