2018-03-26ath10k: debugfs support to get final TPC stats for 10.4 variantsMaharaja Kennadyrajan
Export the final Transmit Power Control (TPC) value, which is the minimum of control power and existing TPC value to user space via a new debugfs file "tpc_stats_final" to help with debugging. It works with the new wmi cmd and event introduced in 10.4 firmware branch.

2018-03-26ath10k: add sta rx packet stats per tidVasanthakumar Thiagarajan
Added per tid sta counters for the following - Total number MSDUs received from firmware - Number of MSDUs received with errors like decryption, crc, mic ,etc. - Number of MSDUs dropped in the driver - A-MPDU/A-MSDU subframe stats - Number of MSDUS passed to mac80211 All stats other than A-MPDU stats are only for received data frames. A-MPDU stats might have stats for management frames when monitor interface is active where management frames are notified both in wmi and HTT interfaces. These per tid stats can be enabled with tid bitmask through a debugfs like below echo <tid_bitmask> > /sys/kernel/debug/ieee80211/phyX/ath10k/sta_tid_stats_mask tid 16 (tid_bitmask 0x10000) is used for non-qos data/management frames The stats are read from /sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/<sta_mac>/dump_tid_stats Sample output: To enable rx stats for tid 0, 5 and 6, echo 0x00000061 > /sys/kernel/debug/ieee80211/phy0/ath10k/sta_tid_stats_mask cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan15/stations/8c\:fd\:f0\:0a\:8e\:df/dump_tid_stats Driver Rx pkt stats per tid, ([tid] count) ------------------------------------------ MSDUs from FW [00] 2567 [05] 3178 [06] 1089 MSDUs unchained [00] 0 [05] 0 [06] 0 MSDUs locally dropped:chained [00] 0 [05] 0 [06] 0 MSDUs locally dropped:filtered [00] 0 [05] 0 [06] 0 MSDUs queued for mac80211 [00] 2567 [05] 3178 [06] 1089 MSDUs with error:fcs_err [00] 0 [05] 0 [06] 2 MSDUs with error:tkip_err [00] 0 [05] 0 [06] 0 MSDUs with error:crypt_err [00] 0 [05] 0 [06] 0 MSDUs with error:peer_idx_inval [00] 0 [05] 0 [06] 0 A-MPDU num subframes upto 10 [00] 2567 [05] 3178 [06] 1087 A-MPDU num subframes 11-20 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 21-30 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 31-40 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 41-50 [00] 0 [05] 0 [06] 0 A-MPDU num subframes 51-60 [00] 0 [05] 0 [06] 0 A-MPDU num subframes >60 [00] 0 [05] 0 [06] 0 A-MSDU num subframes 1 [00] 2567 [05] 3178 [06] 1089 A-MSDU num subframes 2 [00] 0 [05] 0 [06] 0 A-MSDU num subframes 3 [00] 0 [05] 0 [06] 0 A-MSDU num subframes 4 [00] 0 [05] 0 [06] 0 A-MSDU num subframes >4 [00] 0 [05] 0 [06] 0 Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

In netvsc_receive(), it puts the last RNDIS packet's receive status for all packets in a vmxferpage which may contain multiple RNDIS packets.

Paul adds status register reads to reduce a potential race condition where registers can read 0xFFFFFFFF during a PCI reset, which in turn causes the driver to remove the adapter. Then fixes an assignment operation with an "OR" operation. Shannon Nelson provides several IPsec offload cleanups to ixgbe, as well as a patch to enable TSO with IPsec offload. Tony provides the much anticipated XDP support for ixgbevf. Currently, pass, drop and XDP_TX actions are supported, as well as meta data and stats reporting. Björn Töpel tweaks the page counting for XDP_REDIRECT, since a page can have its reference count decreased via the xdp_do_redirect() call. ==================== Signed-off-by: David S.

2018-03-23ixgbe: tweak page counting for XDP_REDIRECTBjörn Töpel
The current page counting scheme assumes that the reference count cannot decrease until the received frame is sent to the upper layers of the networking stack. This assumption does not hold for the XDP_REDIRECT action, since a page (pointed out by xdp_buff) can have its reference count decreased via the xdp_do_redirect call. To work around that, we now start off by a large page count and then don't allow a refcount less than two.

2018-03-23ixgbevf: Add support for XDP_TX actionTony Nguyen
This implements the XDP_TX action which is modeled on the ixgbe implementation. However instead of using CPU id to determine which XDP queue to use, this uses the received RX queue index, which is similar to i40e. Doing this eliminates the restriction that number of CPUs not exceed number of XDP queues that ixgbe has. Also, based on the number of queues available, the number of TX queues may be reduced when an XDP program is loaded in order to accommodate the XDP queues.

2018-03-23ixgbe: enable TSO with IPsec offloadShannon Nelson
Fix things up to support TSO offload in conjunction with IPsec hw offload. This raises throughput with IPsec offload on to nearly line rate.

2018-03-23ixgbe: no need for esp trailer if GSOShannon Nelson
There is no need to calculate the trailer length if we're doing a GSO/TSO, as there is no trailer added to the packet data. Also, don't bother clearing the flags field as it was already cleared earlier.
