-queue Tony Nguyen says: ==================== 10GbE Intel Wired LAN Driver Updates 2022-01-31 Alexander Lobakin says: This is an interpolation of [0] to other Intel Ethernet drivers (and is (re)based on its code). The main aim is to keep XDP metadata not only in case with build_skb(), but also when we do napi_alloc_skb() + memcpy(). All Intel drivers suffers from the same here: - metadata gets lost on XDP_PASS in legacy-rx; - excessive headroom allocation on XSK Rx to skbs; - metadata gets lost on XSK Rx to skbs. Those get especially actual in XDP Hints upcoming. I couldn't have addressed the first one for all Intel drivers due to that they don't reserve any headroom for now in legacy-rx mode even with XDP enabled. This is hugely wrong, but requires quite a bunch of work and a separate series. Luckily, ice doesn't suffer from that. igc has 1 and 3 already fixed in [0].

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
