All,
I am working to add VLAN interface creation over HSR/PRP interface.
It works fine after I fixed the HSR driver to allow creation of
VLAN over it and with VLAN without hw acceleration. But with hw
acceleration, the HSR hook is bypassed in net/core/dev.c as
if (skb_vlan_tag_present(skb)) {
if (pt_prev) {
ret = deliver_skb(skb, pt_prev, orig_dev);
pt_prev = NULL;
}
if (vlan_do_receive(&skb))
goto another_round;
else if (unlikely(!skb))
goto out;
}
rx_handler = rcu_dereference(skb->dev->rx_handler);
if (rx_handler) {
if (pt_prev) {
ret = deliver_skb(skb, pt_prev, orig_dev);
pt_prev = NULL;
}
switch (rx_handler(&skb)) {
case RX_HANDLER_CONSUMED:
ret = NET_RX_SUCCESS;
goto out;
case RX_HANDLER_ANOTHER:
goto another_round;
case RX_HANDLER_EXACT:
deliver_exact = true;
case RX_HANDLER_PASS:
break;
default:
BUG();
}
}
What is the best way to address this issue? With VLAN hw acceleration,
skb_vlan_tag_present(skb) is true and rx_handler() is not called.
Thanks
