The test cases for ip_fast_csum and csum_ipv6_magic were using arbitrary
alignment of data to iterate through random inputs. ip_fast_csum should
have the data aligned along (14 + NET_IP_ALIGN) bytes and
csum_ipv6_magic should have data aligned along 32-bit boundaries.
While this is being changed, fix up the awkward offset code in
test_csum_ipv6_magic and use a struct instead.

So this works on little endian systems. Unfortunately, I still get

Hmm okay it was easy to get this to work on big endian for
test_ip_fast_csum but test_csum_ipv6_magic was trickier. I will send out
a new version with the changes.

Instead of trying to save the expected results why not just
calculate them with a 'really dumb' implementation.
(eg: Add 16bit items and then fold.)
For the generic tests, IIRC:
Your test vectors looked random.
They should probably contain some very specific tests cases.
eg:
- Zero length and all zeros - checksum should be zero (not 0xffff).
- Buffers where the final 'fold' needs the carry added in.

The existing csum test cases have three tests, one for random and then
one for each of the two specific test cases you mentioned. I figured
having the random test case would most likely catch an error if one
existed.
The additional tests can be added in a future patch but I would like to
make sure the existing test cases work first.
