This patch adds a new hash expression, this provides jhash support but
this can be extended to support for other hash functions. The modulus
and seed already comes embedded into this new expression.
Use case example:
... meta mark set hash ip saddr mod 10

The PPTP is encapsulated by GRE header with that GRE_VERSION bits
must contain one. But current GRE RPS needs the GRE_VERSION must be
zero. So RPS does not work for PPTP traffic.
In my test environment, there are four MIPS cores, and all traffic
are passed through by PPTP. As a result, only one core is 100% busy
while other three cores are very idle. After this patch, the usage
of four cores are balanced well.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Use mod_timer_pending() to avoid reactivating a dead expectation in
the h323 conntrack helper, from Liping Zhang.
2) Oneliner to fix a type in the register name defined in the nf_tables
header.
3) Don't try to look further when we find an inactive elements with no
descendants in the rbtree set implementation, otherwise we crash.
4) Handle valid zero CSeq in the SIP conntrack helper, from
Christophe Leroy.
5) Don't display a trailing slash in conntrack helper with no classes
via /proc/net/nf_conntrack_expect, from Liping Zhang.
6) Fix an expectation leak during creation from the nfqueue path, again
from Liping Zhang.
7) Validate netlink port ID in verdict message from nfqueue, otherwise
an injection can be possible. Again from Zhang.
8) Reject conntrack tuples with different transport protocol on
original and reply tuples, also from Zhang.
9) Validate offset and length in nft_exthdr, make sure they are under
sizeof(u8), from Laura Garcia Liebana.

This patch fixes a regression introduced by commit b810253bd9 ("cxl:
Add mechanism for delivering AFU driver specific events").
It changes the type u8 to __u8 in the uapi header cxl.h, because the
former is a kernel internal type, and may not be defined in userland
build environments, in particular when cross-compiling libcxl on x86_64
linux machines (RHEL6.7 and Ubuntu 16.04).
This patch also changes the size of the field data_size, and makes it
constant, to support 32-bit userland applications running on big-endian
ppc64 kernels transparently.
mpe: This is an ABI change, however the ABI was only added during the
4.8 merge window so has never been part of a released kernel - therefore
we give ourselves permission to change it.
