Hello, all,
The attached patch adds a OEM handle and workaround code for Intel
i82751 MAC working in the super pass-though mode which has known
deviations in its RMCP+ implementation. With the OEM handle active,
IPMITool can successfully interact with this Intel 82751-based boards.
Please, review.
Regards,
Dmitry
