Subject: [PATCH] [net-next] net/mlx5e: fix ip6_dst_lookup link failure
Date: Wed, 4 Feb 2026 14:00:49 +0100 [thread overview]
Message-ID: <20260204130057.4107804-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Changing mlx5 to call ip6_dst_lookup() means it now fails to link
when IPv6 is a loadable module but ipsec support is built-in:
ipsec.c:(.text+0x1061): undefined reference to `ip6_dst_lookup'
Add a Kconfig dependency that removes avoids this configuration.
Fixes: e35d7da8dd9e ("net/mlx5e: Use ip6_dst_lookup instead of ipv6_dst_lookup_flow for MAC init")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
