[realtek] Problems with built-in RTL8139CL laptopPC

[YOKOYAMA Hiroki]

Hello all,

I have a laptop PC(SHARP:PC-SX1-H1,built-in LAN interface(RTL8139CL)).
The problem is:
  I can ping itself but, can't ping any other host. 
I'm trying now:
  kernel v.2.4.6
  8139too v.0.9.18

mii-diag returns:

Using the default interface 'eth0'.
Basic registers of MII PHY #32:  0000 0000 0000 0000 0000 0000 0000 0000.
Basic mode control register 0x0000: Auto-negotiation disabled, with
Speed fixed at 10 mbps, half-duplex.
Basic mode status register 0x0000 ... 0000.
  Link status: not established.
Link partner information information is not exchanged when in fixed speed mode.

rtl8139-diag -aammee returns:

The RealTek chip appears to be active, so some registers will not be read.
To see all register values use the '-f' flag.
