...copy mode, when we detect data copied we disable zero copy for a while. With this patch applied, I get the same performance for guest to host and guest to guest both with and without zero copy tx. Changes from v2: change callback parameter from int to bool accordingly, drop err parameter from skb_tx_error Changes from v1: Comment fixups in patches 2 and 8 suggested by Vlad Yasevich, no changes to other patches Michael S.

tun supports zero copy transmit since 0690899b4d4501b3505be069b9a687e68ccbe15b, however you can only enable this mode if you know your workload does not trigger heavy guest to host/host to guest traffic - otherwise you get a (minor) performance regression. This patchset addresses this problem by notifying the owner device when callback is invoked because of a data copy. This makes it possible to
