Subject: Fwd: Kernel panic when using KVM and mlx4_en driver (when bonding and
 sriov enabled)

Hello, I have one bug with new HPE ProLiant m710x Server Cartridges,
there is Mellanox Technologies MT27520 Family [ConnectX-3 Pro]
Ethernet controller.

When I use bonding + VFs and KVM I have stacked kernel with these
messages on console:

[ 1011.070739] kvm [16361]: vcpu0, guest rIP: 0xffffffff810644d8
disabled perfctr wrmsr: 0xc2 data 0xffff
[ 1011.528347] cache_from_obj: Wrong slab cache. kmalloc-256 but
object is from kmalloc-192
[ 1011.927642] general protection fault: 0000 [#1] SMP PTI
[ 1012.185439] cache_from_obj: Wrong slab cache. kmalloc-256 but
object is from kmalloc-192

I've already reported this bug on launchpad:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1755268
But since the bug is present in the latest kernel, I was advised to
contact you directly.

=== Steps to repoduce ===

I have the next network configuration:

eno1 (physical)    eno1d1 (physical)    eno2 (virtual function)
eno2d1 (virtual function)
        |                  |
        +------ bond0 -----+
                  |
                  |
                vmbr0 (bridge)


After my machine is booted, I can run this commands:

# wget http://dl-cdn.alpinelinux.org/alpine/v3.7/releases/x86_64/alpine-virt-3.7.0-x86_64.iso
-O alpine.iso
# qemu-system-x86_64 -machine pc-i440fx-xenial,accel=kvm,usb=off -boot
d -cdrom alpine.iso -m 512 -nographic -device e1000,netdev=net0
-netdev tap,id=net0

And kernel will break down.
