Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "Fixes here and there, a couple new device IDs, as usual: 1) Fix BQL race in dpaa2-eth driver, from Ioana Ciornei. 2) Fix 64-bit division in iwlwifi, from Arnd Bergmann. 3) Fix documentation for some eBPF helpers, from Quentin Monnet. 4) Some UAPI bpf header sync with tools, also from Quentin Monnet. 5) Set descriptor ownership bit at the right time for jumbo frames in stmmac driver, from Aaro Koskinen. 6) Set IFF_UP properly in tun driver, from Eric Dumazet. 7) Fix load/store doubleword instruction generation in powerpc eBPF JIT, from Naveen N. Rao. 8) nla_nest_start() return value checks all over, from Kangjie Lu. 9) Fix asoc_id handling in SCTP after the SCTP_*_ASSOC changes this merge window. From Marcelo Ricardo Leitner and Xin Long. 10) Fix memory corruption with large MTUs in stmmac, from Aaro Koskinen. 11) Do not use ipv4 header for ipv6 flows in TCP and DCCP, from Eric Dumazet. 12) Fix topology subscription cancellation in tipc, from Erik Hugne. 13) Memory leak in genetlink error path, from Yue Haibing. 14) Valid control actions properly in packet scheduler, from Davide Caratti. 15) Even if we get EEXIST, we still need to rehash if a shrink was delayed. From Herbert Xu. 16) Fix interrupt mask handling in interrupt handler of r8169, from Heiner Kallweit. 17) Fix leak in ehea driver, from Wen Yang" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (168 commits) dpaa2-eth: fix race condition with bql frame accounting chelsio: use BUG() instead of BUG_ON(1) net: devlink: skip info_get op call if it is not defined in dumpit net: phy: bcm54xx: Encode link speed and activity into LEDs tipc: change to check tipc_own_id to return in tipc_net_stop net: usb: aqc111: Extend HWID table by QNAP device net: sched: Kconfig: update reference link for PIE net: dsa: qca8k: extend slave-bus implementations net: dsa: qca8k: remove leftover phy accessors dt-bindings: net: dsa: qca8k: support internal mdio-bus dt-bindings: net: dsa: qca8k: fix example net: phy: don't clear BMCR in genphy_soft_reset bpf, libbpf: clarify bump in libbpf version info bpf, libbpf: fix version info and add it to shared object rxrpc: avoid clang -Wuninitialized warning tipc: tipc clang warning net: sched: fix cleanup NULL pointer exception in act_mirr r8169: fix cable re-plugging issue net: ethernet: ti: fix possible object reference leak net: ibm: fix possible object reference leak ...
