Merge tag 'net-5.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from netfilter and can.

  Current release - new code bugs:

   - tcp: add a missing sk_defer_free_flush() in tcp_splice_read()

   - tcp: add a stub for sk_defer_free_flush(), fix CONFIG_INET=n

   - nf_tables: set last expression in register tracking area

   - nft_connlimit: fix memleak if nf_ct_netns_get() fails

   - mptcp: fix removing ids bitmap setting

   - bonding: use rcu_dereference_rtnl when getting active slave

   - fix three cases of sleep in atomic context in drivers: lan966x, gve

   - handful of build fixes for esoteric drivers after netdev->dev_addr
     was made const

  Previous releases - regressions:

   - revert "ipv6: Honor all IPv6 PIO Valid Lifetime values", it broke
     Linux compatibility with USGv6 tests

   - procfs: show net device bound packet types

   - ipv4: fix ip option filtering for locally generated fragments

   - phy: broadcom: hook up soft_reset for BCM54616S

  Previous releases - always broken:

   - ipv4: raw: lock the socket in raw_bind()

   - ipv4: decrease the use of shared IPID generator to decrease the
     chance of attackers guessing the values

   - procfs: fix cross-netns information leakage in /proc/net/ptype

   - ethtool: fix link extended state for big endian

   - bridge: vlan: fix single net device option dumping

   - ping: fix the sk_bound_dev_if match in ping_lookup"
