Add support for older kernels
Tested working properly back to 4.4
Disabled aliasing for kernels <4.15
Required, as these kernels do not have netdevice aliasing
Use the correct format specifier for (s)size_t
Resolves a compile-time warning on 32-bit
Check the return type of copy_from_user
Resolves a compile-time warning on ARM
Standardize kernel version checking
Requires icsscand >= v2.0.1
icsscand v2.0.0 will not work with older kernels, and would display an obscure error
