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

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

[Anders Roxell]

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

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

This should build without CONFIG_IPV6 too.

Hi Ka-cheong,
Can you please loot at it ? I know you modified
lookup function to take always in6_addr now, but
probably hashing with '__inet_ehashfn' should
work too for non IPV6 address(s).

Santosh

I guess for now, let's add this dependency first.  I
will do a follow up patch to remove this dependency.

Thanks.

You probably meant :

        depends on INET && IPV6

Hmm... Yes, I'll send out a new patch to fix it.

I'm sorry.
