Index:	/sys/<many>, /usr/src/etc/<several> 2.11BSD

Description:
Repeat-By:
Fix:
	See part 0 (the README) for the Description, the Reason and
	the instructions on how update your system.

This is part 5 of 22

The external packet area for the [T]MSCP drivers is allocated here.
Enough room is allocated to handle 2 TMSCP plus 2 MSCP controllers.

The reference to 'ubmap' was removed, it's defined in uba.h.
