functions to allow multiple handler threads read upcall)"
changes its type from U32 to UNSPEC, but leave the kernel
unchanged
and after kernel 6e237d099fac "(netlink: Relax attr validation
for fixed length types)", this bug is exposed by the below
warning
[ 57.215841] netlink: 'ovs-vswitchd': attribute type 5 has an invalid length.
