* cfg80211/mac80211: revert to stack allocation for sinfoJohannes Berg2018-05-183-93/+48Star
| | | | | | | | | Arend's previous patch made the sinfo structure smaller again by to dynamically allocating the per-tid stats only when needed. Thus, revert to stack allocation for the struct to simplify the code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* cfg80211: dynamically allocate per-tid stats for station infoArend van Spriel2018-05-184-6/+27
| | | | | | | | | | | | | | | | With the addition of TXQ stats in the per-tid statistics the struct station_info grew significantly. This resulted in stack size warnings due to the structure itself being above the limit for the warnings. Add an allocation function that those who want to provide per-tid stats should use to allocate the tid array, i.e. struct station_info::pertid.

* mac80211: ethtool: avoid 32 bit multiplication overflowColin Ian King2018-05-081-2/+2
| | | | | | | | | | | | | The multiplication of 100000 * cfg80211_calculate_bitrate() is a 32 bit operation and can overflow if cfg80211_calculate_bitrate is greater than 42949. Although I don't believe this is occurring at present, it would be safer to avoid the potential overflow by making the constant 100000 an ULL to ensure a 64 multiplication occurs.

* cfg80211: average ack rssi support for data framesBalaji Pothunoori2018-05-073-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Average ack rssi will be given to userspace via NL80211 interface if firmware is capable. Userspace tool ‘iw’ can process this information and give the output as one of the fields in ‘iw dev wlanX station dump’. Example output : localhost ~ #iw dev wlan-5000mhz station dump Station 34:f3:9a:aa:3b:29 (on wlan-5000mhz) inactive time: 5370 ms rx bytes: 85321 rx packets: 576 tx bytes: 14225 tx packets: 71 tx retries: 0 tx failed: 2 beacon loss: 0 rx drop misc: 0 signal: -54 dBm signal avg: -53 dBm tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2 rx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2 avg ack signal: -56 dBm authorized: yes authenticated: yes associated: yes preamble: short WMM/WME: yes MFP: no TDLS peer: no DTIM period: 2 beacon interval:100 short preamble: yes short slot time:yes connected time: 203 seconds Main use case is to measure the signal strength of a connected station to AP. Data packet transmit rates and bandwidth used by station can vary a lot even if the station is at fixed location, especially if the rates used are multi stream(2stream, 3stream) rates with different bandwidth(20/40/80 Mhz). These multi stream rates are sensitive and station can use different transmit power for each of the rate and bandwidth combinations. RSSI measured from these RX packets on AP will be not stable and can vary a lot with in a short time. Whereas 802.11 ack frames from station are sent relatively at a constant rate (6/12/24 Mbps) with constant bandwidth(20 Mhz). So average rssi of the ack packets is good and more accurate.

* cfg80211: Call reg_notifier for self managed hints conditionallyAmar Singhal2018-05-071-4/+29
| | | | | | | | | | | | | | | | | | | | Currently the regulatory core does not call the regulatory callback reg_notifier for self managed wiphys, but regulatory_hint_user() call is independent of wiphy and is meant for all wiphys in the system. Even a self managed wiphy may be interested in regulatory_hint_user() to know the country code from a trusted regulatory domain change like a cellular base station. Therefore, for the regulatory source NL80211_REGDOM_SET_BY_USER and the user hint type NL80211_USER_REG_HINT_CELL_BASE, call the regulatory notifier. No current wlan driver uses the REGULATORY_WIPHY_SELF_MANAGED flag while also registering the reg_notifier regulatory callback, therefore there will be no impact on existing drivers without them being explicitly modified to take advantage of this new possibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | lockdep does not know that the locks used by IPv4 defrag and IPv6 reassembly units are of different classes.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch implement the 'Device Naming' feature of the Hyper-V network device API. In Hyper-V on the host through the GUI or PowerShell it is possible to enable the device naming feature which causes the host to make available to the guest the name of the device. This shows up in the RNDIS protocol as the friendly name. The name has no particular meaning and is limited to 256 characters. The value can only be set via PowerShell on the host, but could be scripted for mass deployments. The default value is the string 'Network Adapter' and since that is the same for all devices and useless, the driver ignores it. In Windows, the value goes into a registry key for use in SNMP ifAlias. For Linux, this patch puts the value in the network device alias property; where it is visible in ip tools and SNMP. The host provided ifAlias is just a suggestion, and can be overridden by later ip commands. Also requires exporting dev_set_alias in netdev core.

| * net: netcp: add api to support set rx mode in netcp modulesWingMan Kwok2018-04-192-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an API to support setting rx mode in netcp modules. If a netcp module needs to be notified when upper layer transitions from one rx mode to another and react accordingly, such a module will implement the new API set_rx_mode added in this patch. Currently rx modes supported are PROMISCUOUS and NON_PROMISCUOUS modes. Signed-off-by: WingMan Kwok <w-kwok2@ti.com> Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | The netcp driver shouldn't proceed until the knav qmss and dma devices are ready. So return -EPROBE_DEFER if these devices are not ready. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | As the probe sequence is not guaranteed contrary to the assumption of the commit 2d8e276a9030, same has to be reverted. commit 2d8e276a9030 ("net: netcp: remove dead code from the driver") Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S.

| * net: netcp: ethss: use of_get_phy_mode() to support different RGMII modesMurali Karicheri2018-04-191-0/+18
| | | | | | | | | | | | | | | | | | | | The phy used for K2G allows for internal delays to be added optionally to the clock circuitry based on board desing. To add this support, enhance the driver to use of_get_phy_mode() to read the phy-mode from the phy device and pass the same to phy through of_phy_connect().

| * net: netcp: ethss: re-use stats handling code for 2u hardwareMurali Karicheri2018-04-191-1/+1
| | | | | | | | | | | | | | | | | | The stats block in 2u cpsw hardware is similar to the one on nu and hence handle it in a similar way by using a macro that includes 2u hardware as well. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | The driver currently support only vlan priority zero. So map the vlan priorities to zero flow in hardware. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | 2u cpsw hardware on K2G uses rgmii link to interface with Phy. So add support for this interface in the code so that driver can be re-used for 2u hardware. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * net: netcp: ethss: make sgmii configuration conditionalMurali Karicheri2018-04-191-5/+13
| | | | | | | | | | | | | | | | | | | | As a preparatory patch to add support for 2u cpsw hardware found on K2G SoC, make sgmii configuration conditional. This is required since 2u uses RGMII interface instead of SGMII and to allow for driver re-use. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S.
