Merge tag 'net-6.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Including fixes from CAN and WPAN. Still quite a few bugs from this release. This pull is a bit smaller because major subtrees went into the previous one. Or maybe people took spring break off? Current release - regressions: - phy: micrel: correct KSZ9131RNX EEE capabilities and advertisement Current release - new code bugs: - eth: wangxun: fix vector length of interrupt cause - vsock/loopback: consistently protect the packet queue with sk_buff_head.lock - virtio/vsock: fix header length on skb merging - wpan: ca8210: fix unsigned mac_len comparison with zero Previous releases - regressions: - eth: stmmac: don't reject VLANs when IFF_PROMISC is set - eth: smsc911x: avoid PHY being resumed when interface is not up - eth: mtk_eth_soc: fix tx throughput regression with direct 1G links - eth: bnx2x: use the right build_skb() helper after core rework - wwan: iosm: fix 7560 modem crash on use on unsupported channel Previous releases - always broken: - eth: sfc: don't overwrite offload features at NIC reset - eth: r8169: fix RTL8168H and RTL8107E rx crc error - can: j1939: prevent deadlock by moving j1939_sk_errqueue() - virt: vmxnet3: use GRO callback when UPT is enabled - virt: xen: don't do grant copy across page boundary - phy: dp83869: fix default value for tx-/rx-internal-delay - dsa: ksz8: fix multiple issues with ksz8_fdb_dump - eth: mvpp2: fix classification/RSS of VLAN and fragmented packets - eth: mtk_eth_soc: fix flow block refcounting logic Misc: - constify fwnode pointers in SFP handling" * tag 'net-6.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (55 commits) net: ethernet: mtk_eth_soc: add missing ppe cache flush when deleting a flow net: ethernet: mtk_eth_soc: fix L2 offloading with DSA untag offload net: ethernet: mtk_eth_soc: fix flow block refcounting logic net: mvneta: fix potential double-frees in mvneta_txq_sw_deinit() net: dsa: sync unicast and multicast addresses for VLAN filters too net: dsa: mv88e6xxx: Enable IGMP snooping on user ports only xen/netback: use same error messages for same errors test/vsock: new skbuff appending test virtio/vsock: WARN_ONCE() for invalid state of socket virtio/vsock: fix header length on skb merging bnxt_en: Add missing 200G link speed reporting bnxt_en: Fix typo in PCI id to device description string mapping bnxt_en: Fix reporting of test result in ethtool selftest i40e: fix registers dump after run ethtool adapter self test bnx2x: use the right build_skb() helper net: ipa: compute DMA pool size properly net: wwan: iosm: fixes 7560 modem crash net: ethernet: mtk_eth_soc: fix tx throughput regression with direct 1G links ice: fix invalid check for empty list in ice_sched_assoc_vsi_to_agg() ice: add profile conflict check for AVF FDIR ...
