Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) CAN fixes from Martin Kelly (cancel URBs properly in all the CAN usb drivers). 2) Revert returning -EEXIST from __dev_alloc_name() as this propagates to userspace and broke some apps. From Johannes Berg. 3) Fix conn memory leaks and crashes in TIPC, from Jon Malloc and Cong Wang. 4) Gianfar MAC can't do EEE so don't advertise it by default, from Claudiu Manoil. 5) Relax strict netlink attribute validation, but emit a warning. From David Ahern. 6) Fix regression in checksum offload of thunderx driver, from Florian Westphal. 7) Fix UAPI bpf issues on s390, from Hendrik Brueckner. 8) New card support in iwlwifi, from Ihab Zhaika. 9) BBR congestion control bug fixes from Neal Cardwell. 10) Fix port stats in nfp driver, from Pieter Jansen van Vuuren. 11) Fix leaks in qualcomm rmnet, from Subash Abhinov Kasiviswanathan. 12) Fix DMA API handling in sh_eth driver, from Thomas Petazzoni. 13) Fix spurious netpoll warnings in bnxt_en, from Calvin Owens. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (67 commits) net: mvpp2: fix the RSS table entry offset tcp: evaluate packet losses upon RTT change tcp: fix off-by-one bug in RACK tcp: always evaluate losses in RACK upon undo tcp: correctly test congestion state in RACK bnxt_en: Fix sources of spurious netpoll warnings tcp_bbr: reset long-term bandwidth sampling on loss recovery undo tcp_bbr: reset full pipe detection on loss recovery undo tcp_bbr: record "full bw reached" decision in new full_bw_reached bit sfc: pass valid pointers from efx_enqueue_unwind gianfar: Disable EEE autoneg by default tcp: invalidate rate samples during SACK reneging can: peak/pcie_fd: fix potential bug in restarting tx queue can: usb_8dev: cancel urb on -EPIPE and -EPROTO can: kvaser_usb: cancel urb on -EPIPE and -EPROTO can: esd_usb2: cancel urb on -EPIPE and -EPROTO can: ems_usb: cancel urb on -EPIPE and -EPROTO can: mcba_usb: cancel urb on -EPROTO usbnet: fix alignment for frames with no ethernet header tcp: use current time in tcp_rcv_space_adjust() ...
