Subject: Re: [PATCH net] pktgen: be friendly to LLTX devices

From: Daniel Borkmann <>
Date: Fri, 11 Apr 2014 13:22:00 +0200

> Similarly to commit 43279500deca ("packet: respect devices with
> LLTX flag in direct xmit"), we can basically apply the very same
> to pktgen. This will help testing against LLTX devices such as
> dummy driver (or others), which only have a single netdevice txq
> and would otherwise require locking their txq from pktgen side
> while e.g. in dummy case, we would not need any locking. Fix this
> by making use of HARD_TX_{UN,}LOCK API, so that NETIF_F_LLTX will
> be respected.
