From 07ce4064677806e330599ade772a914f500e74af Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Fri, 23 Feb 2007 23:36:39 +0100 Subject: r8169: add hooks for per-device hw_start handler Rationale: rtl8169_hw_start will not help maintaining an unified driver for different chipsets but people at Realtek are probably too polite to say it distinctly. Let's add the hook and keep hw_start handler unchanged. As can be seen from the content of rtl8169_pci_tbl, the RTL_CFG_1 entry in rtl_cfg_info was unused. I recycled it for the 0x8168.
