May be something like this:
net/ipv4/arp.c
/*
 *     Special case: We must set Frame Relay source Q.922 address
 */
        if (dev_type == ARPHRD_DLCI) {
                sha = dev->broadcast;
                if (arp->ar_op == __constant_htons(ARPOP_InREQUEST)) {
                        /*
                         * Use fib_lookup in order to comply with
                         * address selection in rfc2390 - 7.1 and
                         * set tip consequently
                         */
                        ...
                } else if (arp->ar_op == __constant_htons(ARPOP_InREPLY))
                        arp->ar_op = ARPOP_REPLY;
        }

Then one forces ARPOP_InREQUEST to follow the same path as ARPOP_REQUEST,
arp_send(ARPOP_InREPLY,...) being the sole difference.
               ^^
Remarks ?
