2018-07-31virtio-net: correctly update XDP_TX countersJason Wang
Commit 5b8f3c8d30a6 ("virtio_net: Add XDP related stats") tries to count TX XDP stats in virtnet_receive(). This will cause several issues: - virtnet_xdp_sq() was called without checking whether or not XDP is set. This may cause out of bound access when there's no enough txq for XDP. - Stats were updated even if there's no XDP/XDP_TX. Fixing this by reusing virtnet_xdp_xmit() for XDP_TX which can counts TX XDP counter itself and remove the unnecessary tx stats embedded in rx stats.

2018-07-31brcmfmac: specify some features per firmware versionRafał Miłecki
Some features supported by firmware aren't advertised and there is no way for a driver to query them. This includes e.g. monitor mode details. Most firmwares support monitor interface but only the latest ones /announce/ it with a "monitor" flag in the "cap" iovar. There isn't any reliable detection method for older firmwares (BRCMF_C_MONITOR was tried but "it only indicates the core part of the stack supports"). Similarly support for tagging monitor frames and building radiotap headers can't be reliably detected for all firmwares. This commit adds table that allows mapping features to firmware version. It adds mappings for 43602a1 and 4366b1 firmwares from linux-firmware.git. Both were confirmed to be passing monitor frames.

2018-07-30hv_netvsc: Add per-cpu ethtool stats for netvscYidong Ren
This patch implements following ethtool stats fields for netvsc: cpu<n>_tx/rx_packets/bytes cpu<n>_vf_tx/rx_packets/bytes Corresponding per-cpu counters already exist in current code. Exposing these counters will help troubleshooting performance issues. for_each_present_cpu() was used instead of for_each_possible_cpu(). for_each_possible_cpu() would create very long and useless output. It is still being used for internal buffer, but not for ethtool output. There could be an overflow if cpu was added between ethtool call netvsc_get_sset_count() and netvsc_get_ethtool_stats() and netvsc_get_strings(). (still safe if cpu was removed) ethtool makes these three function calls separately. As long as we use ethtool, I can't see any clean solution. Currently and in foreseeable short term, Hyper-V doesn't support cpu hot-plug. Plus, ethtool is for admin use. Unlikely the admin would perform such combo operations. Changes in v2: - Remove cpp style comment - Resubmit after freeze Changes in v3: - Reimplemented with kvmalloc instead of alloc_percpu Changes in v4: - Fixed inconsistent array size - Use kvmalloc_array instead of kvmalloc Signed-off-by: Yidong Ren <yidren@microsoft.com> Reviewed-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: David S.

2018-07-29NET: stmmac: align DMA stuff to largest cache line lengthEugeniy Paltsev
As for today STMMAC_ALIGN macro (which is used to align DMA stuff) relies on L1 line length (L1_CACHE_BYTES). This isn't correct in case of system with several cache levels which might have L1 cache line length smaller than L2 line. This can lead to sharing one cache line between DMA buffer and other data, so we can lose this data while invalidate DMA buffer before DMA transaction. Fix that by using SMP_CACHE_BYTES instead of L1_CACHE_BYTES for aligning. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
