If TX channels are set to 4 and RX channels are set to less than 4, using ethtool -L, the driver will try to initialize more RX channels than it has allocated, causing an oops. This fix only initializes the RX ring if it has been allocated. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
