Pull networking fixes from Paolo Abeni:
"Including fixes from can.
Still no major regressions, most of the changes are still due to data
races fixes, plus the usual bunch of drivers fixes.
Previous releases - regressions:
- tcp/udp: make early_demux back namespacified.
- dsa: fix issues with vlan_filtering_is_global
Previous releases - always broken:
- ip: fix data-races around ipv4_net_table (round 2, 3 & 4)
- amt: fix validation and synchronization bugs
- can: fix detection of mcp251863
- eth: iavf: fix handling of dummy receive descriptors
- eth: lan966x: fix issues with MAC table
- eth: stmmac: dwmac-mediatek: fix clock issue
Misc:
- dsa: update documentation"
