Subject: [PATCH] uapi, seg6_iptunnel: Add missing include in seg6_iptunnel.h

From: Ioana-Ruxandra Stăncioi <stancioi@...gle.com>

Include <linux/ipv6.h> in uapi/linux/seg6_iptunnel.h to fix the
following linux/seg6_iptunnel.h compilation error:

   invalid application of 'sizeof' to incomplete type 'struct ipv6hdr'
       head = sizeof(struct ipv6hdr);
                     ^~~~~~

This is to allow including this header in places where <linux/ipv6.h>
has not been included but __KERNEL__ is defined. In the kernel the easy
workaround is including <linux/ipv6.h>, but the header may also be used
by code analysis tools.
