Pull networking fixes from Jakub Kicinski:
 "Rather small batch this time.

  Current release - regressions:

   - bcm63xx_enet: fix sporadic kernel panic due to queue length
     mis-accounting

  Current release - new code bugs:

   - bcm4908_enet: fix RX path possible mem leak

   - bcm4908_enet: fix NAPI poll returned value

   - stmmac: fix missing spin_lock_init in visconti_eth_dwmac_probe()

   - sched: cls_flower: validate ct_state for invalid and reply flags

  Previous releases - regressions:

   - net: introduce CAN specific pointer in the struct net_device to
     prevent mis-interpreting memory

   - phy: micrel: set soft_reset callback to genphy_soft_reset for
     KSZ8081

   - psample: fix netlink skb length with tunnel info

  Previous releases - always broken:

   - icmp: pass zeroed opts from icmp{,v6}_ndo_send before sending

   - wireguard: device: do not generate ICMP for non-IP packets

   - mptcp: provide subflow aware release function to avoid a mem leak

   - hsr: add support for EntryForgetTime

   - r8169: fix jumbo packet handling on RTL8168e

   - octeontx2-af: fix an off by one in rvu_dbg_qsize_write()

   - i40e: fix flow for IPv6 next header (extension header)

   - phy: icplus: call phy_restore_page() when phy_select_page() fails

   - dpaa_eth: fix the access method for the dpaa_napi_portal"
