Only a new fragmentation is inserted between the original one and the ethernet header. The code must therefore make sure that it has a writable region of this size in the skbuff head. But it is not useful to always reallocate the skbuff by this size even when there would be more than enough headroom still in the skb. The reallocation is just to costly during in this codepath.

[batman-adv] master: batman-adv: Reserve needed_*room for fragments (0966d542)

Repository : ssh://git@diktynna/batman-adv On branch : master >--------------------------------------------------------------- commit 0966d5424bb87e863037301488519ccdd69e4d26 Author: Sven Eckelmann <sven(a)narfation.org> Date: Wed Nov 25 13:16:43 2020 +0100 batman-adv: Reserve needed_*room for fragments The batadv net_device is trying to propagate the needed_headroom and needed_tailroom from the lower devices. This is needed to avoid cost intensive reallocations using pskb_expand_head during the transmission. But the fragmentation code split the skb's without adding extra room at the end/beginning of the various fragments. This reduced the performance of transmissions over complex scenarios (batadv on vxlan on wireguard) because the lower devices had to perform the reallocations at least once.
