2020-11-18i40e: Remove unnecessary sw_ring access from xsk TxMagnus Karlsson1-5/+1
Remove the unnecessary access to the software ring for the AF_XDP zero-copy driver. This was used to record the length of the packet so that the driver Tx completion code could sum this up to produce the total bytes sent. This is now performed during the transmission of the packet, so no need to record this in the software ring.

Daniel Borkmann says: ==================== pull-request: bpf-next 2020-11-14 1) Add BTF generation for kernel modules and extend BTF infra in kernel e.g. support for split BTF loading and validation, from Andrii Nakryiko. 2) Support for pointers beyond pkt_end to recognize LLVM generated patterns on inlined branch conditions, from Alexei Starovoitov. 3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh. 4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage infra, from Martin KaFai Lau. 5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the XDP_REDIRECT path, from Lorenzo Bianconi. 6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI context, from Song Liu. 7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build for different target archs on same source tree, from Jean-Philippe Brucker. 8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet. 9) Move functionality from test_tcpbpf_user into the test_progs framework so it can run in BPF CI, from Alexander Duyck. 10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner. Note that for the fix from Song we have seen a sparse report on context imbalance which requires changes in sparse itself for proper annotation detection where this is currently being discussed on linux-sparse among developers [0].

2020-11-13mlxsw: spectrum_router: Pass non-register proto enum to ↵Jiri Pirko1-6/+8
__mlxsw_sp_router_set_abort_trap() Don't pass RALXX register enum and rather pass enum mlxsw_sp_l3proto to __mlxsw_sp_router_set_abort_trap(). This is in preparation to fib entry pack implementation by XMDR register.

2020-11-13usbnet: switch to core handling of rx/tx byte/packet countersHeiner Kallweit1-16/+7
Use netdev->tstats instead of a member of usbnet for storing a pointer to the per-cpu counters. This allows us to use core functionality for statistics handling. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-11-13qtnfmac: switch to core handling of rx/tx byte/packet countersHeiner Kallweit4-70/+20
Use netdev->tstats instead of a member of qtnf_vif for storing a pointer to the per-cpu counters. This allows us to use core functionality for statistics handling. The driver sets netdev->needs_free_netdev, therefore freeing the per-cpu counters at the right point in time is a little bit tricky. Best option seems to be to use the ndo_init/ndo_uninit callbacks.
