+Subject: icmp: allow icmpv6_ndo_send to work with CONFIG_IPV6=n
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+commit a8e41f6033a0c5633d55d6e35993c9e2005d872f upstream.
+
+The icmpv6_send function has long had a static inline implementation
+with an empty body for CONFIG_IPV6=n, so that code calling it doesn't
+need to be ifdef'd. The new icmpv6_ndo_send function, which is intended
+for drivers as a drop-in replacement with an identical function
+signature, should follow the same pattern. Without this patch, drivers
+that used to work with CONFIG_IPV6=n now result in a linker error.
+
+Cc: Chen Zhou <chenzhou10@huawei.com>
+Reported-by: Hulk Robot <hulkci@huawei.com>
+Fixes: 0b41713b6066 ("icmp: introduce helper for nat'd source address in network device context")
