I'd suggest
config IF_IPV6
bool
depends on INET
depends on !(INFINIBAND = y && IPV6 = m)
default y
and then you can use it not only for the above:
config INFINIBAND_ADDR_TRANS
bool
depends on IF_IPV6
default y
but also use it in the source code as a more readable version:

ie use
#ifdef CONFIG_IF_IPV6
here instead.
