2022-04-20net: atlantic: Implement xdp control planeTaehee Yoo1-3/+3
aq_xdp() is a xdp setup callback function for Atlantic driver. When XDP is attached or detached, the device will be restarted because it uses different headroom, tailroom, and page order value. If XDP enabled, it switches default page order value from 0 to 2. Because the default maximum frame size is still 2K and it needs additional area for headroom and tailroom. The total size(headroom + frame size + tailroom) is 2624. So, 1472Bytes will be always wasted for every frame. But when order-2 is used, these pages can be used 6 times with flip strategy. It means only about 106Bytes per frame will be wasted. Also, It supports xdp fragment feature. MTU can be 16K if xdp prog supports xdp fragment. If not, MTU can not exceed 2K - ETH_HLEN - ETH_FCS. And a static key is added and It will be used to call the xdp_clean handler in ->poll(). data plane implementation will be contained the followed patch.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski1-2/+2
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

We introduce internal aq_rxpage wrapper over regular page where extra field is tracked: rxpage offset inside of allocated page. This offset allows to reuse one page for multiple packets. When needed (for example with large frames processing), allocated pageorder could be customized. This gives even larger page reuse efficiency. page_ref_count is used to track page users. If during rx refill underlying page has users, we increase pg_off by rx frame size thus the top half of the page is reused.
