Description 
rge driver doesn't support RTL8101E suspend and resume currently.
When doing S/R, the device will lose its PCI base address configuration.
"scanpci -v" output is as follows:
pci bus 0x0003 cardnum 0x00 function 0x00: vendor 0x10ec device 0x8136
 Realtek Semiconductor Co., Ltd. RTL8101E PCI Express Fast Ethernet controller
  STATUS    0x0010  COMMAND 0x0047
  CLASS     0x02 0x00 0x00  REVISION 0x01
  BIST      0x00  HEADER 0x00  LATENCY 0x00  CACHE 0x08
  BASE0     0x00000002  addr 0x00000000  I/O
  BASE2     0x0000000000000000  addr 0x0000000000000000  MEM 64BIT
  MAX_LAT   0x00  MIN_GNT 0x00  INT_PIN 0x01  INT_LINE 0x07
  BYTE_0    0x01  BYTE_1  0x48  BYTE_2  0xc2  BYTE_3  0xf7
The pci-e configuration space lost problem mentioned above is actually a PCI-E framework issue. It has nothing to do with rge driver. Another issue discovered is that rge can't receive any packets after resuming.
