* Note that CONFIG_MODVERSIONS=n since v4.9-rc4. It was causing i386
modprobe issues because the CRC for some assembler variables were not
being correctly computed. Linus disabled it altogether for 2 rc's,
then restored it at the end in combination with some patches that
set CRC to 0 for assembler variables. I chose to leave it disabled
in light of the Ubuntu policy to revise the package ABI on every upload.

Title:
IP-over-DDP packets dropped
Status in linux package in Ubuntu:
Fix Released
Bug description:
Ubuntu's kernel is compiled with CONFIG_IPDDP=m, which, because of an
upstream bug, means that IP-over-DDP packets (DDP type 22) are
silently dropped. This is true even if the generated "ipddp" module
is not loaded; so if this module is compiled, there is no way to
listen for these packets.
One solution would be to fix the module. Another (what CentOS appears
to do?) would be to not compile the "ipddp" module at all -- remove
CONFIG_IPDDP from the kernel's config.
Copying from the upstream bug for specific details:
https://bugzilla.kernel.org/show_bug.cgi?id=115031
"""
When a kernel is compiled with "ipddp" as a module, but the module is not
loaded, DDP packets of type 22 (IP-over-DDP) are silently dropped.
Steps to reproduce:
1. Compile a kernel with 'ipddp' as a module. Do not load the module; make
sure it is not loaded, just compiled.
2. Open up a DDP listening socket for packets of type 22, on any supported
network interface. (Tested with Ethernet.)
3. Attempt to connect to and send data to this socket
Expected behavior:
- If module is loaded, packets will be unwrapped by the kernel and emitted as
IP packets (so will not be received by the listening DDP socket)
- If module is not present, packets will be passed through to the listening
DDP socket
Actual behavior:
- If module is not present but was compiled during the kernel build process,
packets are silently discarded by the kernel
- If module is not present and was not compiled during the kernel build
process, packets are passed through as expected
