Subject: net: rtl8169: Add initialized eth_device structure
X-Git-Tag: v2010.12-rc2~78
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f4eaef7b2e4b0b6f2fd6b7120d57804c226997e0;p=u-boot

net: rtl8169: Add initialized eth_device structure

rtl8169 does not have write_hwaddr function.
However, eth stuff executes write_hwaddr function
because eth_device structure has not been initialized.
