Hi Arnd,

I love your patch! Yet something to improve:

[auto build test ERROR on linus/master]
[also build test ERROR on v4.18-rc2 next-20180629]

        # save the attached .config to linux build tree

All errors (new ones prefixed by >>):

drivers/infiniband/hw/i40iw/i40iw_cm.c:2232: undefined reference to `secure_tcpv6_seq'

Fixed this now by added a

        depends on IPV6 || !IPV6

dependency in Kconfig. This ensures that with IPV6=m, i40iw cannot be built-in.

Will send v3 after a little more build testing.
