Router sees wrong MAC address from Linux [SOLVED]

[Tatsh]

I recently redid my entire system but kept the old kernel config and I am using 2.6.20-r10 (yes I know it's unstable). I've messed around with it a bit I guess, and now my router sees a strangely long MAC address instead of the actual one reported by ifconfig. Because I have a few services I like to access while away (VNC, FTP, etc) and internal services (BitTorrent, UT2004, etc), I force my router to give my computer the IP 192.168.0.100 and a few ports are open for it. Everything else is DHCP.

My router sees my MAC address like this:
65746830000100010F1438AF000FB0C2

ifconfig line says this:
eth0 Link encap:Ethernet HWaddr 00:0F:B0:C2:BD:D4

I tested Windows (since I dual-boot), and Windows gets the correct IP address. So I can't but think it's either the kernel configuration or dhcpcd.

[I] net-misc/dhcpcd
Available versions: 2.0.5-r1 3.0.16-r1 3.1.5 3.1.5-r1 ~3.1.6 ~3.1.6-r1 ~3.1.7 ~3.1.8 {build debug static vram zeroconf}
Installed versions: 3.1.5-r1(21:32:50 06/01/0(-vram)

My kernel configuration does have DHCP on and the necessary items enabled.

<*> RealTek RTL-8139 PCI Fast Ethernet Adapter support
<*> RealTek RTL-8139 C+ PCI Fast Ethernet Adapter support

No special options are enabled for "RealTek RTL-8139 PCI Fast Ethernet Adapter support".

I actually booted my old kernel to see if that was it, and the same problem happened. That nearly eliminates the idea that it's the kernel for me. Something is not broadcasting the MAC address properly to the router. Not sure what to try next.

EDIT: Solved the problem. USE="vram" emerge dhcpcd did the trick.

Ah, thanks for that post, I was having the same problem. I don't remember ever having this problem before... was something changed in the default profile or something?

Stranger for me since the last install, where I obviously had to have emerged dhcpcd, it worked fine. Not even sure what the vram use flag does, but it fixes the problem, so I'm not caring much.
