android / phone stuff

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
