Hi,
When compiling the openvswitch datapath module with "make rpm-fedora-kmod"
on the latest CentOS kernels that have the vulnerability fixes
for Zombieload / MDS, it fails with the following errors:
make -C /lib/modules/3.10.0-957.21.3.el7.x86_64/build
M=/home/neubauer/git/ovs/rpm/rpmbuild/BUILD/openvswitch-2.11.90/_3.10.0-957.21.3.el7.x86_64/datapath/linux
modules

As wel are dependent on the STT portion of the module we cannot upgrade
until we can compile the custom openvswitch module, has anyone else run
into this error?
