-Subject: [PATCH] e1000: fail early for evil descriptor
-
-During procss_tx_desc(), driver can try to chain data descriptor with
-legacy descriptor, when will lead underflow for the following
-calculation in process_tx_desc() for bytes:
-
-            if (tp->size + bytes > msh)
-                bytes = msh - tp->size;
-
-This will lead a infinite loop. So check and fail early if tp->size if
-greater or equal to msh.
