Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net into master
Pull networking fixes from David Miller: 1) Fix RCU locaking in iwlwifi, from Johannes Berg. 2) mt76 can access uninitialized NAPI struct, from Felix Fietkau. 3) Fix race in updating pause settings in bnxt_en, from Vasundhara Volam. 4) Propagate error return properly during unbind failures in ax88172a, from George Kennedy. 5) Fix memleak in adf7242_probe, from Liu Jian. 6) smc_drv_probe() can leak, from Wang Hai. 7) Don't muck with the carrier state if register_netdevice() fails in the bonding driver, from Taehee Yoo. 8) Fix memleak in dpaa_eth_probe, from Liu Jian. 9) Need to check skb_put_padto() return value in hsr_fill_tag(), from Murali Karicheri. 10) Don't lose ionic RSS hash settings across FW update, from Shannon Nelson. 11) Fix clobbered SKB control block in act_ct, from Wen Xu. 12) Missing newlink in "tx_timeout" sysfs output, from Xiongfeng Wang. 13) IS_UDPLITE cleanup a long time ago, incorrectly handled transformations involving UDPLITE_RECV_CC. From Miaohe Lin. 14) Unbalanced locking in netdevsim, from Taehee Yoo. 15) Suppress false-positive error messages in qed driver, from Alexander Lobakin. 16) Out of bounds read in ax25_connect and ax25_sendmsg, from Peilin Ye. 17) Missing SKB release in cxgb4's uld_send(), from Navid Emamdoost. 18) Uninitialized value in geneve_changelink(), from Cong Wang. 19) Fix deadlock in xen-netfront, from Andera Righi. 19) flush_backlog() frees skbs with IRQs disabled, so should use dev_kfree_skb_irq() instead of kfree_skb(). From Subash Abhinov Kasiviswanathan. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (111 commits) drivers/net/wan: lapb: Corrected the usage of skb_cow dev: Defer free of skbs in flush_backlog qrtr: orphan socket in qrtr_release() xen-netfront: fix potential deadlock in xennet_remove() flow_offload: Move rhashtable inclusion to the source file geneve: fix an uninitialized value in geneve_changelink() bonding: check return value of register_netdevice() in bond_newlink() tcp: allow at most one TLP probe per flight AX.25: Prevent integer overflows in connect and sendmsg cxgb4: add missing release on skb in uld_send() net: atlantic: fix PTP on AQC10X AX.25: Prevent out-of-bounds read in ax25_sendmsg() sctp: shrink stream outq when fails to do addstream reconf sctp: shrink stream outq only when new outcnt < old outcnt AX.25: Fix out-of-bounds read in ax25_connect() enetc: Remove the mdio bus on PF probe bailout net: ethernet: ti: add NETIF_F_HW_TC hw feature flag for taprio offload net: ethernet: ave: Fix error returns in ave_init drivers/net/wan/x25_asy: Fix to make it work ipvs: fix the connection sync failed in some cases ...
