To: davem; +Cc: netdev, Ariel.Elior, chad.dupuis, manish.rangankar
The patch adds driver support for processing TLV requests/repsonses
from the mfw and upper driver layers respectively. The implementation
reads the requested TLVs from the shared memory, requests the values
from upper layer drivers, populates this info (TLVs) shared memory and
notifies MFW about the TLV values.

Assignments to this pointer are cast hundreds of times, like:

Over and over again.
Just make p_val a void pointer, and then you don't need any of the
casts at all.

MFW requests the TLVs in interrupt context. Extracting of the required
data from upper layers and populating of the TLVs require process context.
The patch adds work-queues for processing the tlv requests. It also adds
the implementation for requesting the tlv values from appropriate protocol
driver.
