Makes sense, will do. How about calling it INFINIBAND_USE_IPV6 or
something like that, though? (Since it's under the INFINIBAND config
stuff and exists to forbid INFINIBAND=y && IPV6=m trying to use IPv6).
But see below:

this doesn't make sense, does it? Your CONFIG_IF_IPV6 will be set in
the case IPV6=n too I think. (Which is the whole point... we want to
build this code, just without IPv6 support, if IPv6 is turned off
completely)

- R.
