/*
 * The miniport block is basically the internal NDIS handle. We need
 * to define this because, unfortunately, it is not entirely opaque
 * to NDIS drivers. For one thing, it contains the function pointer
 * to the NDIS packet receive handler, which is invoked out of the
 * NDIS block via a macro rather than a function pointer. (The
 * NdisMIndicateReceivePacket() routine is a macro rather than
 * a function.) For another, the driver maintains a pointer to the
 * miniport block and passes it as a handle to various NDIS functions.
 * (The driver never really knows this because it's hidden behind
 * an ndis_handle though.)
 *
 * The miniport block has two parts: the first part contains fields
 * that must never change, since they are referenced by driver
 * binaries through macros. The second part is ignored by the driver,
 * but contains various things used internaly by NDIS.SYS. In our
 * case, we define the first 'immutable' part exactly as it appears
 * in Windows, but don't bother duplicating the Windows definitions
 * for the second part. Instead, we replace them with a few BSD-specific
 * things.
