Pull networking fixes from Jakub Kicinski:
"Including fixes from bpf and netfilter.
Current release - regressions:
- bpf: fix crash due to out of bounds access into reg2btf_ids
- mvpp2: always set port pcs ops, avoid null-deref
- eth: marvell: fix driver load from initrd
- eth: intel: revert "Fix reset bw limit when DCB enabled with 1 TC"
Current release - new code bugs:
- mptcp: fix race in overlapping signal events
Previous releases - regressions:
- xen-netback: revert hotplug-status changes causing devices to not
be configured
- dsa:
- avoid call to __dev_set_promiscuity() while rtnl_mutex isn't
held
- fix panic when removing unoffloaded port from bridge
- dsa: microchip: fix bridging with more than two member ports
Previous releases - always broken:
- bpf:
- fix crash due to incorrect copy_map_value when both spin lock
and timer are present in a single value
- fix a bpf_timer initialization issue with clang
- do not try bpf_msg_push_data with len 0
- add schedule points in batch ops
- nf_tables:
- unregister flowtable hooks on netns exit
- correct flow offload action array size
- fix a couple of memory leaks
- vsock: don't check owner in vhost_vsock_stop() while releasing
- gso: do not skip outer ip header in case of ipip and net_failover
- smc: use a mutex for locking "struct smc_pnettable"
- openvswitch: fix setting ipv6 fields causing hw csum failure
- mptcp: fix race in incoming ADD_ADDR option processing
- sysfs: add check for netdevice being present to speed_show
- sched: act_ct: fix flow table lookup after ct clear or switching
zones
- eth: intel: fixes for SR-IOV forwarding offloads
- eth: broadcom: fixes for selftests and error recovery
- eth: mellanox: flow steering and SR-IOV forwarding fixes
Misc:
- make __pskb_pull_tail() & pskb_carve_frag_list() drop_monitor
friends not report freed skbs as drops
- force inlining of checksum functions in net/checksum.h"
