I've built a driver package for you to test, it's in the testing 
repository and files are currently syncing to the mirrors.

kmod-mptfc-3.04.20-1.el7.elrepo.x86_64.rpm

Once files have synced to the mirrors, to install:

yum --enablerepo=elrepo-testing install kmod-mptfc

and you'll probably need to 'modprobe mptfc' or reboot the system.

If you could let me know if it works as expected and then we can promote 
the package to the main repository.

Regards,

Phil
