Networking fixes for 6.6-rc2, including fixes from netfilter and bpf 

Current release - regressions:
 
  - bpf: adjust size_index according to the value of KMALLOC_MIN_SIZE
 
  - netfilter: fix entries val in rule reset audit log
 
  - eth: stmmac: fix incorrect rxq|txq_stats reference
 
 Previous releases - regressions:
 
  - ipv4: fix null-deref in ipv4_link_failure
 
  - netfilter:
    - fix several GC related issues
    - fix race between IPSET_CMD_CREATE and IPSET_CMD_SWAP
 
  - eth: team: fix null-ptr-deref when team device type is changed
 
  - eth: i40e: fix VF VLAN offloading when port VLAN is configured
 
  - eth: ionic: fix 16bit math issue when PAGE_SIZE >= 64KB
 
 Previous releases - always broken:
 
  - core: fix ETH_P_1588 flow dissector
 
  - mptcp: fix several connection hang-up conditions
 
  - bpf:
    - avoid deadlock when using queue and stack maps from NMI
    - add override check to kprobe multi link attach
 
  - hsr: properly parse HSRv1 supervisor frames.
 
  - eth: igc: fix infinite initialization loop with early XDP redirect
 
  - eth: octeon_ep: fix tx dma unmap len values in SG
 
  - eth: hns3: fix GRE checksum offload issue
