Pull networking fixes from Paolo Abeni:
 "Including fixes from bpf, netfilter and WiFi.

  Jakub is doing a lot of work to include the self-tests in our CI, as a
  result a significant amount of self-tests related fixes is flowing in
  (and will likely continue in the next few weeks).

  Current release - regressions:

   - bpf: fix a kernel crash for the riscv 64 JIT

   - bnxt_en: fix memory leak in bnxt_hwrm_get_rings()

   - revert "net: macsec: use skb_ensure_writable_head_tail to expand
     the skb"

  Previous releases - regressions:

   - core: fix removing a namespace with conflicting altnames

   - tc/flower: fix chain template offload memory leak

   - tcp:
      - make sure init the accept_queue's spinlocks once
      - fix autocork on CPUs with weak memory model

   - udp: fix busy polling

   - mlx5e:
      - fix out-of-bound read in port timestamping
      - fix peer flow lists corruption

   - iwlwifi: fix a memory corruption

  Previous releases - always broken:

   - netfilter:
      - nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress
        basechain
      - nft_limit: reject configurations that cause integer overflow

   - bpf: fix bpf_xdp_adjust_tail() with XSK zero-copy mbuf, avoiding a
     NULL pointer dereference upon shrinking

   - llc: make llc_ui_sendmsg() more robust against bonding changes

   - smc: fix illegal rmb_desc access in SMC-D connection dump

   - dpll: fix pin dump crash for rebound module

   - bnxt_en: fix possible crash after creating sw mqprio TCs

   - hv_netvsc: calculate correct ring size when PAGE_SIZE is not 4kB

  Misc:

   - several self-tests fixes for better integration with the netdev CI

   - added several missing modules descriptions"
