ipvlan devices calls netif_inherit_tso_max() to get the tso_max_size/segs from the lower device, so when lower device supports BIG TCP, the ipvlan devices support it too. We also should consider its iph tot_len accessing. Signed-off-by: Xin Long <lucien.xin@gmail.com> --- drivers/net/ipvlan/ipvlan_core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
