[PATCH 2.6.19.2] r8169: support RTL8169SC/8110SC
From: ???
Date: Fri Feb 02 2007 - 03:18:30 EST
From: Edward Hsu <edward_hsu@xxxxxxxxxxx>
patch-r8169-6.001.00 is for /driver/net/r8169.c to support
RTL8169SC/8110SC,
which is a new Realtek Gigabit PCI Ethernet Controller. RTL8110SC's PCI DID
is 0x8167, while RTL8110S and RTL8110SB share 0x8169.
