Merge tag 'net-6.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from bluetooth, can and IPsec.

  Current release - regressions:

   - net: add net.core.qdisc_max_burst

   - can: propagate CAN device capabilities via ml_priv

  Previous releases - regressions:

   - dst: fix races in rt6_uncached_list_del() and
     rt_del_uncached_list()

   - ipv6: fix use-after-free in inet6_addr_del().

   - xfrm: fix inner mode lookup in tunnel mode GSO segmentation

   - ip_tunnel: spread netdev_lockdep_set_classes()

   - ip6_tunnel: use skb_vlan_inet_prepare() in __ip6_tnl_rcv()

   - bluetooth: hci_sync: enable PA sync lost event

   - eth: virtio-net:
      - fix the deadlock when disabling rx NAPI
      - fix misalignment bug in struct virtnet_info

  Previous releases - always broken:

   - ipv4: ip_gre: make ipgre_header() robust

   - can: fix SSP_SRC in cases when bit-rate is higher than 1 MBit.

   - eth:
      - mlx5e: profile change fix
      - octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollback
      - macvlan: fix possible UAF in macvlan_forward_source()"
