HI, that is an old client, and yes the firmware v6.25 is very old.
This client not really supports the ASF Power actions (RMCP), and the problem with “state” report also the problem of firmware. As I know the problem with incorrect reporting of “state” was fixed in firmware version 7.15 or higher. I unable to find the firmware update somewhere on web, and seems it is only one possible solution exist: request the newer firmware for this NIC (Seems 5751) from the DELL or from Broadcom. Also the specific utility for firmware update is needed.
About the RMCP actions: it totally disabled on this kind of clients. It can be checked if you install the Broadcom Advanced Control Suite (BACS) and check the “View ASF!” in tools menu. If the RMCP_% tables are “0” then it means that the RMCP actions are not available even if them are reported from the client as supported.
Theoretically this also could be changed but only with some very specific utilities from Broadcom, that also should be requested from them (or from vendor) with instructions how that can be enabled on client.
