Prasad J Pandit 34e29ce754 net: pcnet: check rx/tx descriptor ring length 
The AMD PC-Net II emulator has set of control and status(CSR)
registers. Of these, CSR76 and CSR78 hold receive and transmit
descriptor ring length respectively. This ring length could range
from 1 to 65535. Setting ring length to zero leads to an infinite
loop in pcnet_rdra_addr() or pcnet_transmit(). Add check to avoid it.
