I recently build gentoo-3.10.7-gentoo-r1 and after reboot i got some network interfaces AND I don't know IF i NEED THEM EVEN;
Please tell me if any or all of them are useful . also I want to find out which kernel feature; that I enabled ; make each one of them, in order to disable them.
By the way i build in the kernel the ability of .config file

Try Vendor/Ethernet/Bluetooth MAC Address Lookup and Search

Example:
dummy0: No match
enp3s0:
Prefix Vendor
08606E ASUSTek COMPUTER INC.
This is Indeed the Ethernet on Your motherboard.

wlp5s0:
Prefix Vendor
F8D111 TP-LINK TECHNOLOGIES CO., LTD.

tun/tap is used for VPN

If the system worked before, and you do not know why you have the new interfaces, you probably do not need them. You can remove support for dummy0, gre0, sit0, and gretap0. You might or might not need tun10.

the problem is that i do not know what is the kernel option CONFIG_??? in the kernel related to each interface. if i knew i would remove them from kernel

I expect this is not just your kernel but also due to UDEV. You should check the news article "Upgrading udev to version >=200". In short, if you create the file /etc/udev/rules.d/80-net-name-slot.rules and reboot enp3s0 might be eth0 again.
