            Description

            In several places acd_..() functions are called without checking if acd is active. This is checked within the functions itself. Due to this, even when using lwIP without ACD, the acd code must be placed in RAM for XIP firmwares. This wastes RAM memory space.

            If instead, the check "if (netif->acd != NULL)"  is made before calling the acd_() functions, the acd_() function can be moved to XIP area for firmwares not using the feature to save RAM memory space.

            This point mainly affects netX52 XIP firmwares.
