[PATCH] net/rds/Kconfig: RDS should depend on IPV6

From: Anders Roxell
Date: Wed Jul 25 2018 - 18:20:18 EST

Build error, implicit declaration of function __inet6_ehashfn shows up
When RDS is enabled but not IPV6.
net/rds/connection.c: In function ârds_conn_bucketâ:
net/rds/connection.c:67:9: error: implicit declaration of function â__inet6_ehashfnâ; did you mean â__inet_ehashfnâ? [-Werror=implicit-function-declaration]
hash = __inet6_ehashfn(lhash, 0, fhash, 0, rds_hash_secret);

Current code adds IPV6 as a depends on in config RDS.

Fixes: eee2fa6ab322 ("rds: Changing IP address internal representation to struct in6_addr")
