X-Git-Tag: firefly_0821_release~31522^2~20^2~4^2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e81c73596704793e73e6dbb478f41686f15a4b34;p=firefly-linux-kernel-4.4.55.git [NET]: Fix MAX_HEADER setting. MAX_HEADER is either set to LL_MAX_HEADER or LL_MAX_HEADER + 48, and this is controlled by a set of CONFIG_* ifdef tests. It is trying to use LL_MAX_HEADER + 48 when any of the tunnels are enabled which set hard_header_len like this: dev->hard_header_len = LL_MAX_HEADER + sizeof(struct xxx); The correct set of tunnel drivers which do this are: ipip ip_gre ip6_tunnel sit so make the ifdef test match. Noticed by Patrick McHardy and with help from Herbert Xu. Signed-off-by: David S.
