GigaBit Ethernet / Protocol Interface Module


This module converts IEEE Gigabit signals to 16 bit data and back.
The Ethernet/UDP/SDDS packets are optional.  The FPGA/MAC chip on the 
module implements the protocol to offload the rest of the card for 
processing.  The IOM=xxx parameter controls the packet handling modes
of the card as follows:

 IOM=UDPXD	- UDP input module
 IOM=DXUDP	- UDP output module
 IOM=SDDSXD	- SDDS input module (use UOPT flag for raw packet)
 IOM=DXSDDS	- SDDS output module

In SDDS configurations, the SDDS header is normally stripped off.
Data is expanded to 16 bits internally and can be read as 1, 8, or
16 bits regardless of the SDDS packet format.  The 16 bit form is
presented to the tuners, and SDDS timecode is handled by the ICE
libraries using the TC=SDDS flag.
