From: Arnd Bergmann <arnd@arndb.de>

When IPv6 is disabled, the flow steering code causes a build failure:

drivers/net/ethernet/mellanox/mlx5/core/en_accel/fs_tcp.c:55:14: error: no member named 'skc_v6_daddr' in 'struct sock_common'; did you mean 'skc_daddr'?
               &sk->sk_v6_daddr, 16);
                    ^
include/net/sock.h:380:34: note: expanded from macro 'sk_v6_daddr'
 #define sk_v6_daddr             __sk_common.skc_v6_daddr

Hide the newly added function in an #ifdef that matches its callers
and the struct member definition.

Fixes: 5229a96e59ec ("net/mlx5e: Accel, Expose flow steering API for rules add/del")

Fix for this was just merged by Linus [NETWORKING PR].

Heh, it appears you managed to create a similar enough patch for the
patchwork bot to confuse the two :)

So to be clear this was not applied :)
