The test cases for ip_fast_csum and csum_ipv6_magic were not properly
aligning the IP header, which were causing failures on architectures
that do not support misaligned accesses like some ARM platforms. To
solve this, align the data along (14 + NET_IP_ALIGN) bytes which is the
standard alignment of an IP header and must be supported by the
architecture.
Furthermore, all architectures except the m68k pad "struct
csum_ipv6_magic_data" to 44 bits. To make compatible with the m68k,
manually pad this structure to 44 bits.
