P J P 737d2b3c41 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.
