2018-07-31mwifiex: use atomic bitops to represent adapter status variablesGanapathi Bhat
Driver is using boolean variables to maintain vairous status information of adapter. These status variables are accessed by multiple threads and there is a possibility of a race. To avoid this, convert these variables to a set of bitops flags, to be operated atomically.

2018-07-31mwifiex: restructure rx_reorder_tbl_lock usageGanapathi Bhat
Driver must ensure that whenever it holds a pointer to the list entry mwifiex_rx_reorder_tbl, it must protect the same with rx_reorder_tbl_lock. At present there are many places where driver does not ensure this. To cover all cases, spinlocks in below funcions are moved out and made sure that the caller will hold the spinlock: mwifiex_11n_dispatch_pkt_until_start_win() mwifiex_11n_scan_and_dispatch() mwifiex_del_rx_reorder_entry() mwifiex_11n_get_rx_reorder_tbl() mwifiex_11n_find_last_seq_num() Signed-off-by: Ganapathi Bhat <gbhat@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-07-31mwifiex: replace rx_pkt_lock by rx_reorder_tbl_lockGanapathi Bhat
At present driver spinlock protects iteration of list rx_reorder_tbl_ptr with rx_reorder_tbl_lock. To protect the individual items in this list, it uses rx_pkt_lock. But, we can use a single rx_reorder_tbl_lock for both purposes. This patch replaces rx_pkt_lock by rx_reorder_tbl_lock.

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.

2018-07-30ath10k: add debugfs file warm_hw_resetMaharaja Kennadyrajan
Debugfs support to do hardware warm reset with WMI command WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi service is enabled in the firmware for backward compatibility). This change is purely for debugging purpose when hardware hangs/mutes. This hardware reset won't affect the connectivity but there will be small pause in data traffic. Here we are doing BB/MAC level reset and hence whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset. So the target will be in the active state.

The tx completion of multiple mgmt frames can be bundled in a single event and sent by the firmware to host, if this capability is not disabled explicitly by the host. If the host cannot handle the bundled mgmt tx completion, this capability support needs to be disabled in the wmi init cmd, sent to the firmware. Add the host capability indication flag in the wmi ready command, to let firmware know the features supported by the host driver. This field is ignored if it is not supported by firmware. Set the host capability indication flag(i.e. host_capab) to zero, for disabling the support of bundle mgmt tx completion. This will indicate the firmware to send completion event for every mgmt tx completion, instead of bundling them together and sending in a single event.

This isn't correct in case of system with several cache levels which might have L1 cache line length smaller than L2 line.

2018-07-28net: mvneta: remove data pointer usage from device_node structureGregory CLEMENT
On year ago Rob Herring wanted to remove the data pointer from the device_node structure[1]. The mvneta driver seemed to be the only one which used (abused ?) it. However, the proposal of Rob to remove this pointer from the driver introduced a regression, and I tested and fixed an alternative way, but it was never submitted as a proper patch. Now here it is: Instead of using the device_node structure ->data pointer, we store the BM private data as the driver data of the BM platform_device. The core mvneta code can retrieve it by doing a lookup on which platform_device corresponds to the BM device tree node using of_find_device_by_node(), and get its driver data [1]https://www.spinics.net/lists/netdev/msg445197.html Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> Signed-off-by: David S.

The mvneta Ethernet driver is used on a few different Marvell SoCs. Some SoCs have per cpu interrupts for Ethernet events. Some SoCs have a single interrupt, independent of the CPU. The driver handles this by having a per CPU napi structure when there are per CPU interrupts, and a global napi structure when there is a single interrupt. When the napi core calls mvneta_poll(), it passes the napi instance. This was not being propagated through the call chain, and instead the per-cpu napi instance was passed to napi_gro_receive() call. This breaks when there is a single global napi instance.

2018-07-28nfp: flower: fix port metadata conversion bugJohn Hurley
Function nfp_flower_repr_get_type_and_port expects an enum nfp_repr_type return value but, if the repr type is unknown, returns a value of type enum nfp_flower_cmsg_port_type. This means that if FW encodes the port ID in a way the driver does not understand instead of dropping the frame driver may attribute it to a physical port (uplink) provided the port number is less than physical port count. Fix this and ensure a net_device of NULL is returned if the repr can not be determined.
