2019-04-25rsi: change in device init frame sequence for 9116Siva Rebbagondla
Initial frame exchange sequence has been changed for 9116 chip. Getting MAC address using EEPROM read frame will be once common device configuration is done and RESET_MAC frame is sending after bootup parameters confirmation is received, which are different from RS9113 device Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-04-25rsi: add firmware loading for 9116 deviceSiva Rebbagondla
New firmware files and firmware loading method are added for 9116. Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-04-25rsi: move common part of firmware load to separate functionSiva Rebbagondla
Till software bootloader ready state, communication with device is common for 9113 and 9116. Hence moved that part of firmware loading to separate function rsi_prepare_fw_load(). Also LMAC_VER_OFFSET is different for 9113 and 9116, so renamed existing macro to LMAC_VER_OFFSET_9113 Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-04-25rsi: add new device model for 9116Siva Rebbagondla
9116 device id entry is added in both SDIO and USB interfaces. New enumberation value taken for the device model. Based on the device model detected run time, few device specific operations needs to be performed. adding rsi_dev_model to get device type in run time, as we can use same driver for 9113 and 9116 except few firmware load changes.

2019-04-25rt2800mmio: use timer and work for handling tx statuses timeoutsStanislaw Gruszka
Sometimes we can get into situation when there are pending statuses, but we do not get INT_SOURCE_CSR_TX_FIFO_STATUS. Handle this situation by arming timeout timer and read statuses (it will fix case when we just do not have irq) and queue work to handle case we missed statues from hardware FIFO.

For unknown reasons printk() on some context can cause CPU hung on embedded MT7620 AP/router MIPS platforms. What can result on wifi disconnects.

2019-04-25rt2x00: check number of EPROTO errorsStanislaw Gruszka
Some USB host devices/drivers on some conditions can always return EPROTO error on submitted URBs. That can cause infinity loop in the rt2x00 driver. Since we can have single EPROTO errors we can not mark as device as removed to avoid infinity loop. However we can count consecutive EPROTO errors and mark device as removed if get lot of it. I choose number 10 as threshold.

2019-04-19iwlwifi: dbg_ini: set dump bit only when trigger collection is certainShahar S Matityahu
In case the the trigger occurrences is zero or force_restart is set, the driver sets IWL_FWRT_STATUS_DUMPING without actually scheduling trigger collection.

2019-04-18Merge branch 'net-add-reset-controller-driven-PHY-reset'David S. Miller
David Bauer says: ==================== net: add reset-controller driven PHY reset This patchset adds support for a PHY reset driven by a reset-controller. Currently, only GPIO driven resets are supported by the PHY subsystem. It also renames the reset-gpio from 'reset' to 'reset_gpio' to better differentiate between resets wired to a GPIO and resets wired to a reset-controller driven pin. Some systems have the PHY reset-line wired to a pin controlled by a reset-controller (eg. some Atheros AR9132 based boards). In case the bootloader asserts reset before loading the kernel, we currently do not have a clean way of deasserting reset to probe the PHY. v3: - add missing newline in mdio_bus.c v2: - fixed missed rename of "reset" in at803x.c - move initial reset to mdio_device_reset ==================== Signed-off-by: David S.

2019-04-18ipv6: Add rate limit mask for ICMPv6 messagesStephen Suryaputra
To make ICMPv6 closer to ICMPv4, add ratemask parameter. Since the ICMP message types use larger numeric values, a simple bitmask doesn't fit. I use large bitmap. The input and output are the in form of list of ranges. Set the default to rate limit all error messages but Packet Too Big. For Packet Too Big, use ratemask instead of hard-coded. There are functions where icmpv6_xrlim_allow() and icmpv6_global_allow() aren't called. This patch only adds them to icmpv6_echo_reply(). Rate limiting error messages is mandated by RFC 4443 but RFC 4890 says that it is also acceptable to rate limit informational messages. Thus, I removed the current hard-coded behavior of icmpv6_mask_allow() that doesn't rate limit informational messages. v2: Add dummy function proc_do_large_bitmap() if CONFIG_PROC_SYSCTL isn't defined, expand the description in ip-sysctl.txt and remove unnecessary conditional before kfree(). v3: Inline the bitmap instead of dynamically allocated. Still is a pointer to it is needed because of the way proc_do_large_bitmap work. Signed-off-by: Stephen Suryaputra <ssuryaextr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-18net: phy: remove dead code from phy_sanitize_settingsHeiner Kallweit
phy_sanitize_settings() is called from phy_start_aneg() only, and only if phydev->autoneg isn't set. Therefore the removed code does nothing. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-18net: phy: don't set autoneg if it's not supportedHeiner Kallweit
In phy_device_create() we set phydev->autoneg = 1. This isn't changed even if the PHY doesn't support autoneg. This seems to affect very few PHY's, and they disable phydev->autoneg in their config_init callback. So it's more of an improvement, therefore net-next. The patch also wouldn't apply to older kernel versions because the link mode bitmaps have been introduced recently. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.
