[openib-general] Where is the programming reference manual of IBG2(OFED)?

Hi,
I'm new to IBG2 programming, It's seems that there's only "Release Notes"
in the package. I need some basic documents about progrmming with IBG2 or
OFED. The specification is too abstract and useless for programming. I
search google but find nothing. Anyone can help? Must I read the sample
code and source code to learn it?
