    Subject[PATCH 03/11] UAPI: virtio_net: Fix use of C++ keywords as structural members
    From
    Date
    The virtio_net_ctrl_hdr struct uses a C++ keyword as structural members.  Fix
    this by inserting an anonymous union that provides an alternative name and
    then hide the reserved name in C++.
