Merge tag 'net-6.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from Bluetooth, CAN and Netfilter.

  Current release - regressions:

   - two fixes for the netdev per-instance locking

   - batman-adv: fix double-hold of meshif when getting enabled

  Current release - new code bugs:

   - Bluetooth: increment TX timestamping tskey always for stream
     sockets

   - wifi: static analysis and build fixes for the new Intel sub-driver

  Previous releases - regressions:

   - net: fib_rules: fix iif / oif matching on L3 master (VRF) device

   - ipv6: add exception routes to GC list in rt6_insert_exception()

   - netfilter: conntrack: fix erroneous removal of offload bit

   - Bluetooth:
       - fix sending MGMT_EV_DEVICE_FOUND for invalid address
       - l2cap: process valid commands in too long frame
       - btnxpuart: Revert baudrate change in nxp_shutdown

  Previous releases - always broken:

   - ethtool: fix memory corruption during SFP FW flashing

   - eth:
       - hibmcge: fixes for link and MTU handling, pause frames etc
       - igc: fixes for PTM (PCIe timestamping)

   - dsa: b53: enable BPDU reception for management port

  Misc:

   - fixes for Netlink protocol schemas"
