Merge tag 'net-6.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "A little calmer than usual, probably just the timing of sub-tree PRs. Including fixes from netfilter. Current release - regressions: - inet: bring NLM_DONE out to a separate recv() again, fix user space which assumes multiple recv()s will happen and gets blocked forever - drv: mlx5: - restore mistakenly dropped parts in register devlink flow - use channel mdev reference instead of global mdev instance for coalescing - acquire RTNL lock before RQs/SQs activation/deactivation Previous releases - regressions: - net: change maximum number of UDP segments to 128, fix virtio compatibility with Windows peers - usb: ax88179_178a: avoid writing the mac address before first reading Previous releases - always broken: - sched: fix mirred deadlock on device recursion - netfilter: - br_netfilter: skip conntrack input hook for promisc packets - fixes removal of duplicate elements in the pipapo set backend - various fixes for abort paths and error handling - af_unix: don't peek OOB data without MSG_OOB - drv: flower: fix fragment flags handling in multiple drivers - drv: ravb: fix jumbo frames and packet stats accounting Misc: - kselftest_harness: fix Clang warning about zero-length format - tun: limit printing rate when illegal packet received by tun dev" * tag 'net-6.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (46 commits) net: ethernet: ti: am65-cpsw-nuss: cleanup DMA Channels before using them net: usb: ax88179_178a: avoid writing the mac address before first reading net: ravb: Fix RX byte accounting for jumbo packets net: ravb: Fix GbEth jumbo packet RX checksum handling net: ravb: Allow RX loop to move past DMA mapping errors net: ravb: Count packets instead of descriptors in R-Car RX path net: ethernet: mtk_eth_soc: fix WED + wifi reset net:usb:qmi_wwan: support Rolling modules selftests: kselftest_harness: fix Clang warning about zero-length format net/sched: Fix mirred deadlock on device recursion netfilter: nf_tables: fix memleak in map from abort path netfilter: nf_tables: restore set elements when delete set fails netfilter: nf_tables: missing iterator type in lookup walk s390/ism: Properly fix receive message buffer allocation net: dsa: mt7530: fix port mirroring for MT7988 SoC switch net: dsa: mt7530: fix mirroring frames received on local port tun: limit printing rate when illegal packet received by tun dev ice: Fix checking for unsupported keys on non-tunnel device ice: tc: allow zero flags in parsing tc flower ice: tc: check src_vsi in case of traffic from VF ...
