Previously, the check to turn on promiscuous mode only took into account the total number of SHared Receive Address (SHRA) registers and if the request was for a register within that range. It is possible that the Management Engine might have locked a number of SHRA and not allowed a new address to be written to the requested register. Add a function to determine the number of unlocked SHRA registers. Then determine if the number of registers available is sufficient for our needs, if not then return -ENOMEM so that UNICAST PROMISC mode is activated. Since the method by which ME claims SHRA registers is non-deterministic, also add a return value to the function attempting to write an address to a SHRA, and return a -E1000_ERR_CONFIG if the write fails. The error will be passed up the function chain and allow the driver to also set UNICAST PROMISC when this happens.
