Subject: Question on bulk dequeue support in virtual drivers
Date: Thu, 20 Nov 2014 05:39:44 -0700 [thread overview]
Message-ID: <546DE110.8060607@openvpn.net> (raw)
Consider a tunneling driver that receives packets in ndo_start_xmit,
encapsulates them in UDP, and forwards via ip_local_out. The
ndo_start_xmit implementation can implement bulking by looking at
skb->xmit_more. But then how to efficiently transmit the resulting
bulked list of encapsulated packets via UDP, so that the packets both
enter and leave the driver in bulked form? Is there an ip_local_out
alternative for bulked skb lists?
