There's a new transmit hash policy being added to the bonding driver that
is a simple XOR of vlan ID and source MAC, xmit_hash_policy vlan+srcmac.
This trivial patch makes it configurable and queryable via iproute2.
$ sudo modprobe bonding mode=2 max_bonds=1 xmit_hash_policy=0
$ sudo ip link set bond0 type bond xmit_hash_policy vlan+srcmac
$ ip -d link show bond0

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
