* Ethernet status, per interface.
|

*
|
||||
* The chip uses two types of pointers: 16 bit and 24 bit
|
||||
* 24 bit pointers cover the board's memory.
|
||||
* 16 bit pointers are offsets from the ISCP's `ie_base'
|
||||
*
|
||||
* The board's memory is represented by the bus handle `bh'. The MI
|
||||
* i82586 driver deals exclusively with offsets relative to the
|
||||
* board memory bus handle. The `ie_softc' fields below that are marked
|
||||
* `MD' are in the domain of the front-end driver; they opaque to the
|
||||
* MI driver part.
|
||||
*
|
||||
* The front-end is required to manage the SCP and ISCP structures. i.e.
|
||||
* allocate room for them on the board's memory, and arrange to point the
|
||||
* chip at the SCB stucture, the offset of which is passed to the MI
|
||||
* driver in `sc_scb'.
|
||||
*
|
||||
* The following functions provide the glue necessary to deal with
|
||||
* host and bus idiosyncracies:
|
||||
*
|
||||
* hwreset - board reset
|
||||
* hwinit - board initialization
|
||||
* chan_attn - get chip to look at prepared commands
|
||||
* intrhook - board dependent interrupt processing
|
||||
*
|
||||
* All of the following shared-memory access function use an offset
|
||||
* relative to the bus handle to indicate the shared memory location.
|
||||
* The bus_{read/write}N function take or return offset into the
|
||||
* shared memory in the host's byte-order.
|
||||
*
|
||||
* memcopyin - copy device memory: board to KVA
|
||||
* memcopyout - copy device memory: KVA to board
|
||||
* bus_read16 - read a 16-bit i82586 pointer
|
||||
`offset' argument will be 16-bit aligned
|
||||
* bus_write16 - write a 16-bit i82586 pointer
|
||||
`offset' argument will be 16-bit aligned
|
||||
* bus_write24 - write a 24-bit i82586 pointer
|
||||
`offset' argument will be 32-bit aligned
|
||||
* bus_barrier - perform a bus barrier operation, forcing
|
||||
all outstanding reads/writes to complete
