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).
Actually, thinking about this for 30 more seconds, I'm not sure how another config symbol helps at all. I do like splitting dependencies onto multiple lines as a replacement for &&, so I have:
config INFINIBAND_ADDR_TRANS bool depends on INET depends on !(INFINIBAND = y && IPV6 = m) default y
right now.
Not sure if it's worth introducing another Kconfig symbol that depends on IPV6 != n to avoid the
#if defined(CONFIG_IPV6) || defined(CONFIG_IPV6_MODULE)
tests. I note that there are tons of that construction all over the tree, and the places without it look somewhat dubious (eg net/ipv4/ip_gre.c looks as if it will do the wrong thing if IPV6=m). Maybe adding CONFIG_IPV6_ENABLED or something and cleaning up the whole tree would be a good janitorial project?
