[PATCH] ebtables: make it be able to work on 64bit kernel with 32 bit userspace

[PATCH] ebtables: make it be able to work on 64bit kernel with 32 bit userspace

[rongqing.li]

From: "Roy.Li" <rongqing.li@windriver.com>


KERNEL_64_USERSPACE_32 should be enabled for 64bit kernel with 32 bit userspace,
otherwise, the date struct(struct ebt_replace, struct ebt_entry_match) have
different alignment size, will make it unable to work.
