/*
 * DMA descriptor structures. The RX and TX descriptor formats are

 * RX and TX queues on multiple controllers, in the case where you have
 * multiple MACs in a switching configuration. With the 83820, the pointer
 * values can be either 64 bits or 32 bits depending on how the chip is
 * configured. For the 83821, the fields are always 32-bits. There is
 * also an optional extended status field for VLAN and TCP/IP checksum
 * functions. We use the checksum feature so we enable the use of this
 * field. Descriptors must be 64-bit aligned.
 * After this, we include some additional structure members for
