- Are packet drivers supposed to be reentrant ?
-
- They can be, but maybe not in the way you hope for.
-
- In particular, is is guaranteed to be safe to call a p.d's send routine
- whilst executing in a receiver upcall ?
-
- You can call send_pkt(), and it should not crash, but it is allowed to fail
- and not send the packet.
-
- The FTP specification I've got doesnt seem to say anything on this.
-
- 1.10 will, if the PPP stuff ever settles down.
