 /*
    Assumptions:
-   - if device has no dev->hard_header routine, it adds and removes ll header
-     inside itself. In this case ll header is invisible outside of device,
-     but higher levels still should reserve dev->hard_header_len.
-     Some devices are enough clever to reallocate skb, when header
-     will not fit to reserved space (tunnel), another ones are silly
-     (PPP).
+   - If the device has no dev->header_ops->create, there is no LL header
+     visible above the device. In this case, its hard_header_len should be 0.
+     The device may prepend its own header internally. In this case, its
+     needed_headroom should be set to the space needed for it to add its
+     internal header.
+     For example, a WiFi driver pretending to be an Ethernet driver should
+     set its hard_header_len to be the Ethernet header length, and set its
+     needed_headroom to be (the real WiFi header length - the fake Ethernet
+     header length).
    - packet socket receives packets with pulled ll header,
      so that SOCK_RAW should push it back.
 
 On receive:
 -----------
 
-Incoming, dev->hard_header!=NULL
+Incoming, dev_has_header(dev) == true
    mac_header -> ll header
    data       -> data
 
-Outgoing, dev->hard_header!=NULL
+Outgoing, dev_has_header(dev) == true
    mac_header -> ll header
    data       -> ll header
 
-Incoming, dev->hard_header==NULL
-   mac_header -> UNKNOWN position. It is very likely, that it points to ll
-		 header.  PPP makes it, that is wrong, because introduce
-		 assymetry between rx and tx paths.
+Incoming, dev_has_header(dev) == false
+   mac_header -> data
+     However drivers often make it point to the ll header.
+     This is incorrect because the ll header should be invisible to us.
    data       -> data
 
-Outgoing, dev->hard_header==NULL
-   mac_header -> data. ll header is still not built!
+Outgoing, dev_has_header(dev) == false
+   mac_header -> data. ll header is invisible to us.
    data       -> data
 
 Resume
-  If dev->hard_header==NULL we are unlikely to restore sensible ll header.
+  If dev_has_header(dev) == false we are unable to restore the ll header,
+    because it is invisible to us.
