phk f8dd9c1116 If the receiver runs out of space for an received frame in the internal 
FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.

We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches.  This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.

This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.

Remove the #ifdef notyet'ed nge_rxeoc() function.

* DMA descriptor structures. The RX and TX descriptor formats are
* deliberately designed to be similar to facilitate passing them between
* 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
* use by the driver. Note that for this structure will be a different
* size on the alpha, but that's okay as long as it's a multiple of 4
* bytes in size.
