Pull networking fixes from Paolo Abeni:
"Smaller than usual with no fixes from any subtree.
Current release - regressions:
- core: fix race of rtnl_net_lock(dev_net(dev))
Previous releases - regressions:
- core: remove the single page frag cache for good
- flow_dissector: fix handling of mixed port and port-range keys
- sched: cls_api: fix error handling causing NULL dereference
- tcp:
- adjust rcvq_space after updating scaling ratio
- drop secpath at the same time as we currently drop dst
- eth: gtp: suppress list corruption splat in gtp_net_exit_batch_rtnl().
Previous releases - always broken:
- vsock:
- fix variables initialization during resuming
- for connectible sockets allow only connected
- eth:
- geneve: fix use-after-free in geneve_find_dev()
- ibmvnic: don't reference skb after sending to VIOS"
* tag 'net-6.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (34 commits)
Revert "net: skb: introduce and use a single page frag cache"
net: allow small head cache usage with large MAX_SKB_FRAGS values
nfp: bpf: Add check for nfp_app_ctrl_msg_alloc()
tcp: drop secpath at the same time as we currently drop dst
net: axienet: Set mac_managed_pm
arp: switch to dev_getbyhwaddr() in arp_req_set_public()

selftests/net/forwarding: Add a test case for tc-flower of mixed port and port-range
flow_dissector: Fix handling of mixed port and port-range keys
geneve: Suppress list corruption splat in geneve_destroy_tunnels().
gtp: Suppress list corruption splat in gtp_net_exit_batch_rtnl().
dev: Use rtnl_net_dev_lock() in unregister_netdev().
net: Fix dev_net(dev) race in unregister_netdevice_notifier_dev_net().
net: Add net_passive_inc() and net_passive_dec().
net: pse-pd: pd692x0: Fix power limit retrieval
MAINTAINERS: trim the GVE entry
gve: set xdp redirect target only when it is available
