Merge tag 'net-5.14-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Networking fixes, including fixes from netfilter, bpf, can and
  ieee802154.

  The size of this is pretty normal, but we got more fixes for 5.14
  changes this week than last week. Nothing major but the trend is the
  opposite of what we like. We'll see how the next week goes..

  Current release - regressions:

   - r8169: fix ASPM-related link-up regressions

   - bridge: fix flags interpretation for extern learn fdb entries

   - phy: micrel: fix link detection on ksz87xx switch

   - Revert "tipc: Return the correct errno code"

   - ptp: fix possible memory leak caused by invalid cast

  Current release - new code bugs:

   - bpf: add missing bpf_read_[un]lock_trace() for syscall program

   - bpf: fix potentially incorrect results with bpf_get_local_storage()

   - page_pool: mask the page->signature before the checking, avoid dma
     mapping leaks

   - netfilter: nfnetlink_hook: 5 fixes to information in netlink dumps

   - bnxt_en: fix firmware interface issues with PTP

   - mlx5: Bridge, fix ageing time

  Previous releases - regressions:

   - linkwatch: fix failure to restore device state across
     suspend/resume

   - bareudp: fix invalid read beyond skb's linear data

  Previous releases - always broken:

   - bpf: fix integer overflow involving bucket_size

   - ppp: fix issues when desired interface name is specified via
     netlink

   - wwan: mhi_wwan_ctrl: fix possible deadlock

   - dsa: microchip: ksz8795: fix number of VLAN related bugs

   - dsa: drivers: fix broken backpressure in .port_fdb_dump

   - dsa: qca: ar9331: make proper initial port defaults

  Misc:

   - bpf: add lockdown check for probe_write_user helper

   - netfilter: conntrack: remove offload_pickup sysctl before 5.14 is
     out

   - netfilter: conntrack: collect all entries in one cycle,
     heuristically slow down garbage collection scans on idle systems to
     prevent frequent wake ups"
