Controller Statistics Block

Controller Statistics Block
This space was used to report network statistics in the original Eagle MACSI implementation for single port Ethernet
support. Statistics for multi-port controllers, or single port implementations not requiring Eagle MACSI compatibility,
should be obtained via the Report Network Statistics IOPB. The contents of this area are undefined for multi-port
controllers, and are overwritten in any case with multiple completed commands.
The Controller Statistics Block contains a variety of statistics concerning the transmission/reception of data from a
single Ethernet port. By default, these statistics are continuously updated. However, these updates are disabled if the
host is using the Multiple Completions Per Interrupt option and has specified a Maximum Group Count less than 13.
This prevents the returned list of IOPB completions from being overwritten by the Controller Statistics Block.
Once the host initializes the controller to any extended level of MACSI over that supported by the Eagle, or any multi-
port support, the contents of this block of memory will be zero-filled, and will not be updated with any further network
statistics. The Report Network Statistics IOPB may be used to obtain network statistics in this case.
