Pull networking fixes from David Miller: "It looks like a decent sized set of fixes, but a lot of these are one liner off-by-one and similar type changes: 1) Fix netlink header pointer to calcular bad attribute offset reported to user. From Pablo Neira Ayuso. 2) Don't double clear PHY interrupts when ->did_interrupt is set, from Heiner Kallweit. 3) Add missing validation of various (devlink, nl802154, fib, etc.) attributes, from Jakub Kicinski. 4) Missing *pos increments in various netfilter seq_next ops, from Vasily Averin. 5) Missing break in of_mdiobus_register() loop, from Dajun Jin. 6) Don't double bump tx_dropped in veth driver, from Jiang Lidong. 7) Work around FMAN erratum A050385, from Madalin Bucur. 8) Make sure ARP header is pulled early enough in bonding driver, from Eric Dumazet. 9) Do a cond_resched() during multicast processing of ipvlan and macvlan, from Mahesh Bandewar. 10) Don't attach cgroups to unrelated sockets when in interrupt context, from Shakeel Butt. 11) Fix tpacket ring state management when encountering unknown GSO types. From Willem de Bruijn. 12) Fix MDIO bus PHY resume by checking mdio_bus_phy_may_suspend() only in the suspend context. From Heiner Kallweit" * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (112 commits) net: systemport: fix index check to avoid an array out of bounds access tc-testing: add ETS scheduler to tdc build configuration net: phy: fix MDIO bus PM PHY resuming net: hns3: clear port base VLAN when unload PF net: hns3: fix RMW issue for VLAN filter switch net: hns3: fix VF VLAN table entries inconsistent issue net: hns3: fix "tc qdisc del" failed issue taprio: Fix sending packets without dequeueing them net: mvmdio: avoid error message for optional IRQ net: dsa: mv88e6xxx: Add missing mask of ATU occupancy register net: memcg: fix lockdep splat in inet_csk_accept() s390/qeth: implement smarter resizing of the RX buffer pool s390/qeth: refactor buffer pool code s390/qeth: use page pointers to manage RX buffer pool seg6: fix SRv6 L2 tunnels to use IANA-assigned protocol number net: dsa: Don't instantiate phylink for CPU/DSA ports unless needed net/packet: tpacket_rcv: do not increment ring index on drop sxgbe: Fix off by one in samsung driver strncpy size arg net: caif: Add lockdep expression to RCU traversal primitive MAINTAINERS: remove Sathya Perla as Emulex NIC maintainer ...
