Merge tag 'net-6.6-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni: "Including fixes from CAN and BPF. We have a regression in TC currently under investigation, otherwise the things that stand off most are probably the TCP and AF_PACKET fixes, with both issues coming from 6.5. Previous releases - regressions: - af_packet: fix fortified memcpy() without flex array. - tcp: fix crashes trying to free half-baked MTU probes - xdp: fix zero-size allocation warning in xskq_create() - can: sja1000: always restart the tx queue after an overrun - eth: mlx5e: again mutually exclude RX-FCS and RX-port-timestamp - eth: nfp: avoid rmmod nfp crash issues - eth: octeontx2-pf: fix page pool frag allocation warning Previous releases - always broken: - mctp: perform route lookups under a RCU read-side lock - bpf: s390: fix clobbering the caller's backchain in the trampoline - phy: lynx-28g: cancel the CDR check work item on the remove path - dsa: qca8k: fix qca8k driver for Turris 1.x - eth: ravb: fix use-after-free issue in ravb_tx_timeout_work() - eth: ixgbe: fix crash with empty VF macvlan list" * tag 'net-6.6-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (54 commits) rswitch: Fix imbalance phy_power_off() calling rswitch: Fix renesas_eth_sw_remove() implementation octeontx2-pf: Fix page pool frag allocation warning nfc: nci: assert requested protocol is valid af_packet: Fix fortified memcpy() without flex array. net: tcp: fix crashes trying to free half-baked MTU probes net/smc: Fix pos miscalculation in statistics nfp: flower: avoid rmmod nfp crash issues net: usb: dm9601: fix uninitialized variable use in dm9601_mdio_read ethtool: Fix mod state of verbose no_mask bitset net: nfc: fix races in nfc_llcp_sock_get() and nfc_llcp_sock_get_sn() mctp: perform route lookups under a RCU read-side lock net: skbuff: fix kernel-doc typos s390/bpf: Fix unwinding past the trampoline s390/bpf: Fix clobbering the caller's backchain in the trampoline net/mlx5e: Again mutually exclude RX-FCS and RX-port-timestamp net/smc: Fix dependency of SMC on ISM ixgbe: fix crash with empty VF macvlan list net/mlx5e: macsec: use update_pn flag instead of PN comparation net: phy: mscc: macsec: reject PN update requests ...
