[PATCH 0/6] Detect reentrant RX casue by loopback

[Jason Wang]

Hi All:

Followed by commit 22dc8663d9 ("net: forbid the reentrant RX"), we
still need to fix the issues casued by loopback mode where the NIC
usually it via calling nc->info->receive() directly.

The fix is to introduce new network helper and check the
queue->delivering.

Thanks
