e1000 net driver update 4/4:

* Documentation/networking/e1000.txt: Updated with new device IDs,
updated parameters, updated known issues section.
* drivers/net/Config.help: Updated with new device IDs.
* Added license for Makefile
* Bug fix: ethtool GEEPROM was using word-addressing rather than
byte-addressing.
* Bug fix: Maximum Memory Read Byte Count in PCI-X config space set to
minimum of what device advertises, and what the BIOS assigns, rather
than the maximum, which is the device's default mode, and is incorrect
and will cause problems for large (jumbo frame) read operations.

-  Driver Hangs Under Heavy Traffic Loads
-  --------------------------------------
+  Inconsistent Driver Behavior Under Heavy Traffic Loads
+  ------------------------------------------------------
 
-  Intel is aware that previously released e1000 drivers may hang under very
-  specific types of heavy traffic loads. This version includes a workaround
-  that resets the adapter automatically if a hang condition is detected. This
-  workaround ensures network traffic flow is not affected when a hang occurs.
+  Adapters based on the Intel 82543 and 82544 LAN controllers may hang (stop
+  transmitting) under certain network conditions. If this occurs a message
+  is logged in the system event log. In addition, the controller is
+  automatically reset, restoring the network connection. To eliminate the
+  potential for the hang change the RxIntDelay parameter to zero. For details
+  on the RxIntDelay parameter see the Command Line Parameters section.
