Tony Nguyen says: ==================== igc: Add support for Frame Preemption Faizal Rahim says: Introduce support for the FPE feature in the IGC driver. The patches aligns with the upstream FPE API: https://patchwork.kernel.org/project/netdevbpf/cover/20230220122343.1156614-1-vladimir.oltean@nxp.com/ https://patchwork.kernel.org/project/netdevbpf/cover/20230119122705.73054-1-vladimir.oltean@nxp.com/ It builds upon earlier work: https://patchwork.kernel.org/project/netdevbpf/cover/20220520011538.1098888-1-vinicius.gomes@intel.com/ The patch series adds the following functionalities to the IGC driver: a) Configure FPE using `ethtool --set-mm`. b) Display FPE settings via `ethtool --show-mm`. c) View FPE statistics using `ethtool --include-statistics --show-mm'. e) Block setting preemptible tc in taprio since it is not supported yet. Existing code already blocks it in mqprio. Tested: Enabled CONFIG_PROVE_LOCKING, CONFIG_DEBUG_ATOMIC_SLEEP, CONFIG_DMA_API_DEBUG, and CONFIG_KASAN 1) selftests 2) netdev down/up cycles 3) suspend/resume cycles 4) fpe verification No bugs or unusual dmesg logs were observed. Ran 1), 2) and 3) with and without the patch series, compared dmesg and selftest logs - no differences found. * '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: igc: add support to get frame preemption statistics via ethtool igc: add support to get MAC Merge data via ethtool igc: block setting preemptible traffic class in taprio igc: add support to set tx-min-frag-size igc: add support for frame preemption verification igc: set the RX packet buffer size for TSN mode igc: use FIELD_PREP and GENMASK for existing RX packet buffer size igc: optimize TX packet buffer utilization for TSN mode igc: use FIELD_PREP and GENMASK for existing TX packet buffer size igc: rename I225_RXPBSIZE_DEFAULT and I225_TXPBSIZE_DEFAULT igc: rename xdp_get_tx_ring() for non-xdp usage net: ethtool: mm: reset verification status when link is down net: ethtool: mm: extract stmmac verification logic into common library net: stmmac: move frag_size handling out of spin_lock ==================== Link: https://patch.msgid.link/20250418163822.3519810-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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 reStructuredText 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.
