multicast or broadcast the packet using eBPF tc hook

Question

I am trying to design a load balancer using ebpf. I want to redirect the incoming packet to different destinations. Although I have used the bpf_clone_redirect helper function to redirect the packet to real/ virtual interfaces and it's working fine. Now I want to redirect the packet to multiple interfaces at once. Here is the piece of code I write to redirect the 1 packet.

    eth->h_dest[0] = 0xb8;
    eth->h_dest[1] = 0x27;
    eth->h_dest[2] = 0xeb;
    eth->h_dest[3] = 0x42;
    eth->h_dest[4] = 0x77;
    eth->h_dest[5] = 0x56;
new_port = ntohs( 5302) ; 
udp->dest= new_port;          //change the destination port

ipaddr = htonl(0xc0a8006c);  // Dest: 192.168.98.108 
iph->daddr = ipaddr;         // Change the destination address 

// Calculate the sum_diff for destination address and Port number

sum = bpf_csum_diff((void *)&old1_daddr , 4,(void *)&ipaddr,4 ,  0);
sum1 = bpf_csum_diff((void *)&old_port , 4,(void *)&new_port,4 ,  0);


ipaddr2 = htonl(0xc0a8006e);  // Dest: 192.168.98.110
iph->daddr = ipaddr2;         // Change the destination address 

//L3 and L4 checksum Update

bpf_l3_csum_replace(skb, IP_CSUM_OFF,  0 , sum,0 );
bpf_l4_csum_replace(skb, UDP_CSUM_OFF , 0, sum +sum1, IS_PSEUDO | sizeof(ipaddr) );

bpf_clone_redirect(skb,  skb->ifindex, 0 ); // Packet forward to the destination 

//Repeat the same functionality 

// Calculate the sum_diff for destination address and Port number

sum = bpf_csum_diff((void *)&old1_daddr , 4,(void *)&ipaddr2,4 ,  0);

//L3 and L4 checksum Update

bpf_l3_csum_replace(skb, IP_CSUM_OFF,  0 , sum,0 );
bpf_l4_csum_replace(skb, UDP_CSUM_OFF , 0, sum, IS_PSEUDO | sizeof(ipaddr2) );

bpf_clone_redirect(skb,  skb->ifindex, 0 ); // Packet forward to the destination 

return TC_ACT_OK;

I am facing the problem to update the MAC address of packet. With the above code i can change the destination address and port number but unable to updat2 the mac address in 2nd clone.
