Rajesh Borundia says:

====================
* "qlcnic: Change 82xx adapter VLAN id endian type".
  - Adapter requires VLAN id in little endian. VLAN id was being
    converted to __le16 and then passed as a parameter. Pass VLAN id
    as u16 and then use cpu_to_le16 at appropriate places. It is
    appropriate for net-next as SR-IOV patches have a dependency on it.
* "qlcnic: Fix loopback test for SR-IOV PF".
  - It is appropriate for net-next as change is needed for SRIOV PF
    only.
* Remaining patches add enhancements to SR-IOV functionality like
  - FLR handling
  - Adapter reset recovery handling
  - iproute2 tool support for configuring MAC address, Tx rate and
    VLAN id.
  - Mailbox polling support for SR-IOV PF in case mailbox interrupts
    are disabled.
====================
