are you asking about something like this? ??

#include <stdint.h>

#define MAC_SIZE    6

uint8_t mac1 [6];
uint8_t mac2 [6];
uint8_t mac3 [6];

uint8_t payload [3*MAC_SIZE];

void
prep (void)
{
    int i = 0;

    for (unsigned n = 0; n < MAC_SIZE; n++)
        payload [i++] = mac1 [n];

    for (unsigned n = 0; n < MAC_SIZE; n++)
        payload [i++] = mac2 [n];

    for (unsigned n = 0; n < MAC_SIZE; n++)
        payload [i++] = mac3 [n];
}
