When enabling SR-IOV on Mellanox devices and setting vxlan tunnel over the PF
device (adding vxlan port to an OVS bridge),
the kernel is crushing as result of the unimplemented ndos:
.ndo_{add,del}_vxlan_port
This issue was fixed in upstream kernel:
9737c6a net/mlx4_en: Add VXLAN ndo calls to the PF net device ops too
I've backported it to 3.16 (by removing the "yet to be introduced"
ndo_gso_check) and attached the backported version here.
The patch was built and tested on top of ubuntu-trusty: abb1293
("UBUNTU: Ubuntu-lts-3.16.0-29.39~14.04.1")
** Affects: linux (Ubuntu)
Importance: Undecided
Status: Incomplete
** Attachment added: "Suggested fix, backported to ubuntu-3.16.0-28"
