Dave writes: "Various fixes, all over the place: 1) OOB data generation fix in bluetooth, from Matias Karhumaa. 2) BPF BTF boundary calculation fix, from Martin KaFai Lau. 3) Don't bug on excessive frags, to be compatible in situations mixing older and newer kernels on each end. From Juergen Gross. 4) Scheduling in RCU fix in hv_netvsc, from Stephen Hemminger. 5) Zero keying information in TLS layer before freeing copies of them, from Sabrina Dubroca. 6) Fix NULL deref in act_sample, from Davide Caratti. 7) Orphan SKB before GRO in veth to prevent crashes with XDP, from Toshiaki Makita. 8) Fix use after free in ip6_xmit, from Eric Dumazet. 9) Fix VF mac address regression in bnxt_en, from Micahel Chan. 10) Fix MSG_PEEK behavior in TLS layer, from Daniel Borkmann. 11) Programming adjustments to r8169 which fix not being to enter deep sleep states on some machines, from Kai-Heng Feng and Hans de Goede. 12) Fix DST_NOCOUNT flag handling for ipv6 routes, from Peter Oskolkov." * gitolite.kernel.org:/pub/scm/linux/kernel/git/davem/net: (45 commits) net/ipv6: do not copy dst flags on rt init qmi_wwan: set DTR for modems in forced USB2 mode clk: x86: Stop marking clocks as CLK_IS_CRITICAL r8169: Get and enable optional ether_clk clock clk: x86: add "ether_clk" alias for Bay Trail / Cherry Trail r8169: enable ASPM on RTL8106E r8169: Align ASPM/CLKREQ setting function with vendor driver Revert "kcm: remove any offset before parsing messages" kcm: remove any offset before parsing messages net: ethernet: Fix a unused function warning. net: dsa: mv88e6xxx: Fix ATU Miss Violation tls: fix currently broken MSG_PEEK behavior hv_netvsc: pair VF based on serial number PCI: hv: support reporting serial number as slot information bnxt_en: Fix VF mac address regression. ipv6: fix possible use-after-free in ip6_xmit() net: hp100: fix always-true check for link up state ARM: dts: at91: add new compatibility string for macb on sama5d3 net: macb: disable scatter-gather for macb on sama5d3 net: mvpp2: let phylink manage the carrier state ...
