Subject: Re: 8169 Intermittent ifup Failure Issue With RTL8102E Chipset in
Intel's New D945GCLF Atom Board (Not the Initial Modprobe Crash, Another
Problem)
Kasper:
If I was to guess (I didn't actually work out which one yours identifies
as), most likely your NIC isn't caught in my check for MAC_VER_13 or
MAC_VER_16, but Francois's patch has:
- dprintk("Set MAC Reg C+CR Offset 0x82h = 0x01h\n");
- RTL_W8(0x82, 0x01);
+ if (tp->mac_version <= RTL_GIGA_MAC_VER_06) {
+ dprintk("Set MAC Reg C+CR Offset 0x82h = 0x01h\n");
+ RTL_W8(0x82, 0x01);
+ }
Which I've got indirectly but checking for 13 & 16.
Regards
