Subject: Link up issue on ethernet/realtek/r8169.c

Hi,

I'm using TP-LINK PCIe NIC card on my PCIe Root Complex.

Probing looks fine by setting:
r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
PCI: enabling device 0000:00:00.0 (0140 -> 0143)
PCI: enabling device 0000:01:00.0 (0140 -> 0143)
r8169 0000:01:00.0 eth0: RTL8168e/8111e at 0xf006a000,
c0:4a:00:07:18:d4, XID 0c200000 IRQ 89
r8169 0000:01:00.0 eth0: jumbo features [frames: 9200 bytes, tx
checksumming: ko]

But I have an issue while in link is up

$ ifconfig 192.168.1.10 up
r8169 0000:01:00.0: Direct firmware load failed with error -2
r8169 0000:01:00.0: Falling back to user helper
r8169 0000:01:00.0 eth0: unable to load firmware patch
rtl_nic/rtl8168e-2.fw (-2)
r8169 0000:01:00.0 eth0: link down

Looks like firmware loading is failed in open call, Can any one
suggest how to debug further.

thanks!

Got the fix! I have updated .config with firmware details from [1]

CONFIG_EXTRA_FIRMWARE="rtl_nic/rtl8168e-2.fw"
CONFIG_EXTRA_FIRMWARE_DIR="/opt"

[1] http://git.exherbo.org/summer/packages/firmware/rtl_nic/index.html

thanks!
