Subject: [PATCH v8 07/11] bpf: add XDP_TX xdp_action for direct forwarding
Date: Tue, 12 Jul 2016 00:51:30 -0700	[thread overview]
Message-ID: <1468309894-26258-8-git-send-email-bblanco@plumgrid.com> (raw)
In-Reply-To: <1468309894-26258-1-git-send-email-bblanco@plumgrid.com>

XDP enabled drivers must transmit received packets back out on the same
port they were received on when a program returns this action.
