Subject: [PATCH v2 net-next 0/2] add page_pool support for page recycling in veth driver
Date: Sat, 22 Apr 2023 20:54:31 +0200 [thread overview]
Message-ID: <cover.1682188837.git.lorenzo@kernel.org> (raw)
Introduce page_pool support in veth driver in order to recycle pages in
veth_convert_skb_to_xdp_buff routine and avoid reallocating the skb through
the page allocator when we run a xdp program on the device and we receive
skbs from the stack.
Change since v1:
- remove page_pool checks in veth_convert_skb_to_xdp_buff() before allocating
the pages
- recycle pages in the hot cache if build_skb fails in
veth_convert_skb_to_xdp_buff()
Lorenzo Bianconi (2):
net: veth: add page_pool for page recycling
net: veth: add page_pool stats
