o 82xx adapter requires VLAN id in little endian format.
  Instead of passing vlan id parameter as __le16, pass the
  parameter as u16 and  use cpu_to_le16 at appropriate places.

o Add support for commands from VF to PF.
o PF validates the commands sent by the VF before sending
  it to adapter.
o vPort is a container of resources. PF creates vPort
  for VFs and attach resources to it. vPort is
  transparent to the VF.
o Separate 83xx TX and RX hardware resource cleanup from 82xx.

o Adapter provides communication channel between VF and PF.
  Any control commands from the VF driver are sent to the PF driver
  through this communication channel. PF driver validates the
  commands before sending them to the adapter. Similarly PF driver
  forwards any control command responses  to the VF driver
  through this communication channel.  Adapter sends message pending
  event to VF or PF when there is an outstanding response or a command
  for VF or PF respectively. When a command or a response is sent over
  a channel VF or PF cannot send another command or a response
  until adapter sends a channel free event. Adapter allocates 1K area to
  VF and  PF each for this communication.
o Commands and  responses are encapsulated in a header. Header determines
  sequence id, number of fragments, fragment number etc.

o Add QLCNIC_SRIOV to Kconfig.
o Provide PCI sysfs hooks to enable and disable SR-IOV.
o Allow enabling only when CONFIG_QLCNIC_SRIOV is defined.
o qlcnic_sriov_pf.c has all the PF related SR-IOV
  functionality.
o qlcnic_sriov_common.c has VF functionality and SR-IOV
  functionality which is common between VF and PF.
o qlcnic_sriov.h is a common header file for SR-IOV defines.
