Bug description:
  Please incorporate the following upstream commits (and necessary pre-
  requisites )to the 4.2 kernel into 15.10, 15.04, 14.04 (including
  HWE), and 12.04 (including HWE). Network throughput is improved with
  proper setting of MTU in virtualized environments.

  hv_netvsc: Add support to set MTU reservation from guest side
  When packet encapsulation is in use, the MTU needs to be reduced for
  headroom reservation.
  The existing code takes the updated MTU value only from the host side.
  But vSwitch extensions, such as Open vSwitch, require the flexibility
  to change the MTU to different values from within a guest during the
  lifecycle of a vNIC, when the encapsulation protocol is changed. The
  patch supports this kind of MTU changes.

  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f9cbce34c34bcc05ea0dd78c8999bfe88b5b6b86

  hv_netvsc: Add close of RNDIS filter into change mtu call
  The current change mtu call only stops tx before removing RNDIS filter.
  In case ringbufer is not empty, the rndis_filter_device_remove() may
  hang on removing the buffers.

  This patch adds close of RNDIS filter before removing it, also a
  gradual waiting loop until the ring is empty. The change_mtu hang
  issue under heavy traffic is solved by this patch.
