Subject: [RFC PATCH 3/7] tun: allow use of BPF_PROG_TYPE_SCHED_CLS program type
Date: Tue, 12 Jan 2021 21:41:39 +0200 [thread overview]
Message-ID: <20210112194143.1494-4-yuri.benditovich@daynix.com> (raw)
In-Reply-To: <20210112194143.1494-1-yuri.benditovich@daynix.com>
This program type can set skb hash value. It will be useful
when the tun will support hash reporting feature if virtio-net.
