capturing both incoming and outgoing packets using raw socket

Question

I am writing a tool in C for logging data usage of different applications running on my Linux system. For this i had created a raw socket and then I bind it with "eth0" which is the name of my interface. But my problem is that, this sockets captures only incoming packets (ie: packets with destination MAC address as my system's MAC address). I can't find any packets that has source MAC address as my system's MAC address. So it means packets written by my own machine are not captured by the raw socket. But i want to capture packets in both directions for identifying uploaded and downloaded data size. Can anybody help?

int main()
{
    int rs,len;
    struct sockaddr_ll addr;
    char buf[65535];

    rs = socket(PF_PACKET,SOCK_RAW,htons(ETH_ALL));
    setsockopt(rs,SOL_SOCKET,SO_BINDDEVICE,"eth0",4);
    while(recvfrom(rs,buf,65535,&addr,&len) > 0){
        //print packets
    }
    return 0;
}

I have found this while searching over your problem. I haven't tried this. May be this will work.

  int v=0;
    v = PACKET_MASK_ANY & ~(1<<PACKET_OUTGOING) & ~(1 << PACKET_LOOPBACK);
    setsockopt( raw_sock, SOL_PACKET, PACKET_RECV_TYPE, &v, sizeof(v));
