I have several pppoe i/f's over one eth i/f and I want to set the
source mac address used by each pppoe i/f to a unique mac address from
user space.
Is this possible? If so, how do I do that?

Try the macvlan driver.

Thanks, but I can't see that it will help.
I am looking for something like this that I currently have added
to pppoe_ioctl() in pppoe.c:
case PPPOEIOCSSRCMAC:
{
struct relay_source_mac smac;
err = -EBUSY;
if (sk->sk_state & (PPPOX_BOUND|PPPOX_ZOMBIE|PPPOX_DEAD))
break;
err = -ENOTCONN;
if (!(sk->sk_state & PPPOX_CONNECTED))
break;
err = -EFAULT;
if (copy_from_user(&smac, (void *) arg, sizeof(smac)))
break;
memcpy(po->srcmac, smac.srcmac, ETH_ALEN);
err = 0;
break;
}
then changed the call to hard_header in __pppoe_xmit() to
dev->hard_header(skb, dev, ETH_P_PPP_SES,
po->pppoe_pa.remote,
po->srcmac, data_len);
Would a new ioctl(PPPOEIOCSSRCMAC) to pppoe be acceptable?

I have several pppoe i/f's over one eth0 i/f and I want to set the
source mac address used by each pppoe i/f to a unique mac address from
user space.
Is this possible? If so, how do I do that?
