CTL_STATUS_t ctl_mac_mii_deferred_read_result(CTL_NET_INTERFACE_t *net);
ctl_mac_mii_deferred_read_result returns the result of the last read of the MII management interface without blocking or busy-wait. This is a wrapper around the mii_deferred_read_result_fn member of the network driver.
Return values are the same as ctl_mac_mii_read: negactive for failure, a number between 0 and 0xFFFF (inclusive) for success.
