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.
