Not All Symbols Present in a Loadable Kernel Module

[David Christensen]

I'm trying to build the "bce" driver as a kernel module under RELENG_7 but I'm
finding that not all of the functions in the driver are exported as symbols.  This
makes it difficult to "call" a function from ddb because I get the error "Symbol
not found".  I'm building and loading the driver from /usr/src/sys/modules/bce.
What am I doing wrong?  How can I get all functions in the driver exported as
symbols usable by the debugger?
