Required menuconfig prompts/settings according to gentoo wiki and my own configs:
Device Drivers ---> [*] Network device support ---> USB Network Adapters ---> <M> Multi-purpose USB Networking Framework -M- CDC Ethernet support (smart devices such as cable modems) <M> CDC EEM support <M> Host for RNDIS and ActiveSync devices (EXPERIMENTAL) <M> Simple USB Network Links (CDC Ethernet subset) [*] Embedded ARM Linux links
- note ***
The prompts above frequently change from one kernel version to the next. The above settings were noted as of kernel version 3.8.3-gentoo-r1.
corresponding .config parameters spawned from above settings:
CONFIG_NETDEVICES=y CONFIG_USB_USBNET=m CONFIG_USB_NET_CDCETHER=m CONFIG_USB_NET_CDC_EEM=m CONFIG_USB_NET_RNDIS_HOST=m CONFIG_USB_NET_CDC_SUBSET=m CONFIG_USB_ARMLINUX=y
- note ***
check config command
cat .config | grep -E "NETDEVICES|USB_USBNET|USB_NET_CDC_SUBSET|USB_NET_CDCETHER|USB_NET_CDC_EEM|NET_RNDIS_HOST|USB_ARMLINUX"
iptables
-*- Networking support ---> Networking options ---> [*] Network packet filtering framework (Netfilter) ---> Core Netfilter Configuration ---> [*] Netfilter connection tracking support -*- Netfilter Xtables support (required for ip_tables) [*] "conntrack" connection tracking match support [*] "state" match support IP: Netfilter Configuration ---> [*] IPv4 connection tracking support (required for NAT) [*] IP tables support (required for filtering/masq/NAT) [*] Packet filtering
