+ * ixgbe_host_interface_command - Issue command to manageability block
+ * @hw: pointer to the HW structure
+ * @buffer: contains the command to write and where the return status will
+ * be placed
+ * @length: length of buffer, must be multiple of 4 bytes
+ * @timeout: time in ms to wait for command completion
+ * @return_data: read and return data from the buffer (true) or not (false)
+ * Needed because FW structures are big endian and decoding of
+ * these fields can be 8 bit or 16 bit based on command. Decoding
+ * is not easily understood without making a table of commands.
+ * So we will leave this up to the caller to read back the data
+ * in these cases.
+ *
+ * Communicates with the manageability block. On success return IXGBE_SUCCESS
+ * else returns semaphore error when encountering an error acquiring
+ * semaphore or IXGBE_ERR_HOST_INTERFACE_COMMAND when command fails.
