The only target still referencing it is omap24xx, and it is marked as
broken.

-    8139cp: Fix GSO MSS handling
-    
-    When fixing the TSO support I noticed we just mask ->gso_size with the
-    MSSMask value and don't care about the consequences.
-    
-    Provide a .ndo_features_check() method which drops the NETIF_F_TSO
-    feature for any skb which would exceed the maximum, and thus forces it
-    to be segmented by software.
-    
-    Then we can stop the masking in cp_start_xmit(), and just WARN if the
-    maximum is exceeded, which should now never happen.
-    
-    Finally, Francois Romieu noticed that we didn't even have the right
-    value for MSSMask anyway; it should be 0x7ff (11 bits) not 0xfff.

-    8139cp: Enable offload features by default
-    
-    I fixed TSO. Hardware checksum and scatter/gather also appear to be
-    working correctly both on real hardware and in QEMU's emulation.
-    
-    Let's enable them by default and see if anyone screams...
