*
|
|
* This macro requires:
|
|
* adapter = a pointer to struct em_shared_adapter
|
|
* status = the 8 bit status field of the RX descriptor with EOP set
|
|
* error = the 8 bit error field of the RX descriptor with EOP set
|
|
* length = the sum of all the length fields of the RX descriptors that
|
|
* make up the current frame
|
|
* last_byte = the last byte of the frame DMAed by the hardware
|
|
* max_frame_length = the maximum frame length we want to accept.
|
|
* min_frame_length = the minimum frame length we want to accept.
|
|
*
|
|
* This macro is a conditional that should be used in the interrupt
|
|
* handler's Rx processing routine when RxErrors have been detected.

*
|
|
* Typical use:
|
|
* ...
|
