Merge tag 'net-6.1-rc9' 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 - new code bugs:

   - bonding: ipv6: correct address used in Neighbour Advertisement
     parsing (src vs dst typo)

   - fec: properly scope IRQ coalesce setup during link up to supported
     chips only

  Previous releases - regressions:

   - Bluetooth fixes for fake CSR clones (knockoffs):
       - re-add ERR_DATA_REPORTING quirk
       - fix crash when device is replugged

   - Bluetooth:
       - silence a user-triggerable dmesg error message
       - L2CAP: fix u8 overflow, oob access
       - correct vendor codec definition
       - fix support for Read Local Supported Codecs V2

   - ti: am65-cpsw: fix RGMII configuration at SPEED_10

   - mana: fix race on per-CQ variable NAPI work_done

  Previous releases - always broken:

   - af_unix: diag: fetch user_ns from in_skb in unix_diag_get_exact(),
     avoid null-deref

   - af_can: fix NULL pointer dereference in can_rcv_filter

   - can: slcan: fix UAF with a freed work

   - can: can327: flush TX_work on ldisc .close()

   - macsec: add missing attribute validation for offload

   - ipv6: avoid use-after-free in ip6_fragment()

   - nft_set_pipapo: actually validate intervals in fields after the
     first one

   - mvneta: prevent oob access in mvneta_config_rss()

   - ipv4: fix incorrect route flushing when table ID 0 is used, or when
     source address is deleted

   - phy: mxl-gpy: add workaround for IRQ bug on GPY215B and GPY215C"
