It's not intuitively obvious that bpfilter_umh is a statically linked binary. Mention the toolchain requirement in the Kconfig help, so people have an easier time figuring out what's needed.

This builds bpfilter kernel module with embedded user mode helper

Note: your toolchain must support building static binaries, since
|
|
rootfs isn't mounted at the time when __init functions are called
|
|
and do_execv won't be able to find the elf interpreter.
