udp: using datalen to cap ipv6 udp max gso segments
The max number of UDP gso segments is intended to cap to UDP_MAX_SEGMENTS, this is checked in udp_send_skb(). skb->len contains network and transport header len here, we should use only data len instead. This is the ipv6 counterpart to the below referenced commit, which missed the ipv6 change Fixes: 158390e45612 ("udp: using datalen to cap max gso segments") Signed-off-by: Coco Li <lixiaoyan@google.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Link: https://lore.kernel.org/r/20211223222441.2975883-1-lixiaoyan@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
