Subject: [PATCH v2 bpf-next 0/3] introduce xdp frags support to veth driver
Date: Tue, 15 Feb 2022 14:08:08 +0100 [thread overview]
Message-ID: <cover.1644930124.git.lorenzo@kernel.org> (raw)
Introduce xdp frags support to veth driver in order to allow increasing the mtu
over the page boundary if the attached xdp program declares to support xdp
fragments. Enable NETIF_F_ALL_TSO when the device is running in xdp mode.
This series has been tested running xdp_router_ipv4 sample available in the
kernel tree redirecting tcp traffic from veth pair into the mvneta driver.
Changes since v1:
- always consider skb paged are non-writable
- fix tpt issue with sctp
- always use napi if we are running in xdp mode in veth_xmit
Lorenzo Bianconi (3):
net: veth: account total xdp_frame len running ndo_xdp_xmit
veth: rework veth_xdp_rcv_skb in order to accept non-linear skb
veth: allow jumbo frames in xdp mode
