The struct ip_options declared in ip.h is only unsed in the optlength
macro which is also defined in ip.h and not used in the driver code.
All other definitions/declarations in ip.h are duplicated from
<include/uapi/linux/ip.h>. Remove the ip.h header file and its includes.

The compiler is free to ignore, or follow, "inline" markings so they
really have no use in .c files, so just remove them.
This allows functions to properly show up as being unused when all
callers to them are removed, otherwise gcc does not warn you about this.

The kernel module failed to build
on arm64 platform. Other platforms like x86 can build without problem
because the csum_ipv6_magic function are defined in arch specific
asm/checksum.h, which is missing on arm64 platform.
