There's no longer an ipt_physdev.c in netfilter, so it must be included in another c file. However I need to use 2.6.16.2x and it seems to be either missing or buggy in there. For example it's in Kconfig, but enabling all the dependencies does not display it in menuconfig, and when you output the .config it's not listed in there at all.
