    net: avoid infinite loop when receiving packets(CVE-2015-5278)
    
    Ne2000 NIC uses ring buffer of NE2000_MEM_SIZE(49152)
    bytes to process network packets. While receiving packets
    via ne2000_receive() routine, a local 'index' variable
    could exceed the ring buffer size, leading to an infinite
    loop situation.
