This patch fixes a VT mode check to make sure VLAN filters are disabled when in promisc mode and VT is not enabled. The problem with the previous check was that: E1000_MRQC_ENABLE_VMDQ is defined as 0x00000003 but when not in VT mode: mrqc |= E1000_MRQC_ENABLE_RSS_4Q (0x00000002) So the above check will trigger regardless if VT mode is being used or not.

If the ready bit in the transmit buffer descriptor (TxBD[R]) is previously detected as not set during a prior frame transmission, then the ENET_TDAR[TDAR] bit is cleared at a later time, even if additional TxBDs were added to the ring and the ENET_TDAR[TDAR] bit is set. This results in frames not being transmitted until there is a 0-to-1 transition on ENET_TDAR[TDAR]. Workarounds: code can use the transmit frame interrupt flag (ENET_EIR[TXF]) as a method to detect whether the ENET has completed transmission and the ENET_TDAR[TDAR] has been cleared. If ENET_TDAR[TDAR] is detected as cleared when packets are queued and waiting for transmit, then a write to the TDAR bit will restart TxBD processing. This case main happen when loading is light. A ethernet package may not send out utile next package put into tx queue. How to test: while [ true ] do ping <IP> -s 10000 -w 4 ping <IP> -s 6000 -w 2 ping <IP> -s 4000 -w 2 ping <IP> -s 10000 -w 2 done You will see below result in overnight test. 6008 bytes from 10.192.242.116: seq=1 ttl=128 time=0.722 ms 4008 bytes from 10.192.242.116: seq=0 ttl=128 time=1001.008 ms 4008 bytes from 10.192.242.116: seq=1 ttl=128 time=1.010 ms 10008 bytes from 10.192.242.116: seq=0 ttl=128 time=0.896 ms After apply this patch, >1000ms delay disappear.

atl1c uses netdev_alloc_skb to refill its rx dma ring, but that call makes no guarantees about the suitability of the memory for use in DMA. As a result we've gotten reports of atl1c drivers occasionally hanging and needing to be reset: https://bugzilla.kernel.org/show_bug.cgi?id=54021 Fix this by modifying the call to use the internal version __netdev_alloc_skb, where you can set the gfp_mask explicitly to include GFP_DMA. Tested by two reporters in the above bug, who have the hardware to validate it. Both report immediate cessation of the problem with this patch Signed-off-by:

usbnet doesn't support yet SG, so drivers should not advertise SG or TSO capabilities, as they allow TCP stack to build large TSO packets that need to be linearized and might use order-5 pages. This adds an extra copy overhead and possible allocation failures. Current code ignore skb_linearize() return code so crashes are even possible. Best is to not pretend SG/TSO is supported, and add this again when/if usbnet really supports SG for devices who could get a performance gain.

John W. Linville says: ==================== This is another batch of fixes intended for the 3.11 stream. FWIW, this is the first request with fixes from the mac80211 and iwlwifi trees as well. Regarding the mac80211 bits, Johannes says: "Here I have a fix for RSSI thresholds in mesh, two minstrel fixes from Felix, an nl80211 fix from Michal and four various fixes I did myself." As for the iwlwifi bits, Johannes says: "Here I have a fix for debugfs directory creation (causing a spurious error message), two scanning fixes from David Spinadel, an LED fix and two patches related to a BA session problem that eventually caused firmware crashes from Emmanuel and a small BT fix for older devices as well as a workaround for a firmware problem with APs with very small beacon intervals from myself." Along with those: Arend van Spriel addresses a lock-up and a NULL pointer dereference in brcmfmac. Daniel Drake fixes an unhandled interrupt during device tear down in mwifiex. Larry Finger corrects a wil6210 build error. Oleksij Rempel fixes two ath9k_htc problems related to keeping the driver and firmware in sync. Solomon Peachy gives us a cw1200 fix to avoid an oops in monitor mode. ==================== Signed-off-by: -

The work queue is initialised in rtl_open (when the interface goes up), but canceled in rtl_remove_one (when the PCI device gets removed). If the network interface is not brought up, then the work queue struct is not initialised. When the device is removed, the attempt to cancel the uninitialised work queue causes a lockdep warning. This patch fixes the issue by moving cancel_work_sync to rtl_close (to match rtl_open). (Note that rtl_close is also called via unregister_netdev in rtl_remove_one.) Signed-off-by:

Since 4bb16672 (build some drivers only when compile-testing), PTP_1588_CLOCK_PCH depends on (X86 || COMPILE_TEST). But PCH_GBE selects PTP_1588_CLOCK_PCH without depending on x86. Fix this by adding the same dependency here. Signed-off-by:

Currently ath9k_htc will reboot firmware only if interface was ever started. Which lead to the problem in case where interface was never started but module need to be reloaded. This patch will partially fix bug "ath9k_htc: Target is unresponsive" https://github.com/qca/open-ath9k-htc-firmware/issues/1 Reproduction case: - plug adapter - make sure nothing will touch it. Stop Networkmanager or blacklist mac address of this adapter. - rmmod ath9k_htc; sleep 1; modprobe ath9k_htc Signed-off-by:

Currently we configure harwdare and clock, only after interface start. In this case, if we reload module or reboot PC without configuring adapter, firmware will freeze. There is no software way to reset adpter. This patch add initial configuration and set it in disabled state, to avoid this freeze. Behaviour of this patch should be similar to: ifconfig wlan0 up; ifconfig wlan0 down. Bug: https://github.com/qca/open-ath9k-htc-firmware/issues/1Tested-by:

During tear down (e.g. mwifiex_sdio_remove during system suspend), mwifiex left IRQs enabled for a significant period of time when it was unable to handle them correctly. This caused interrupt storms and interfered with the bluetooth interface on the same SDIO card. Solve this by disabling interrupts at the point when they can no longer be handled correctly, which is at the start of mwifiex_remove_card(). For cleanliness, we now enable interrupts in the mwifiex_add_card() path, to be symmetrical with the disabling of interrupts. We also couple the registration of the sdio IRQ handler with the actual enable/disable of interrupts at the hardware level. I also removed a write to this register in mwifiex_init_sdio which seemed pointless and won't cause any ill effects now that we only register the SDIO IRQ handler when we are ready to accept interrupts. Includes some corrections from Amitkumar Karwar. Signed-off-by:

John W. Linville says: ==================== Please accept this batch of fixes intended for the 3.11 tree... Alexey Khoroshilov fixes a suspend-related race in ath9k_htc. Arnd Bergmann corrects the alignment of a structure in the ssb code to be compatible with ARM devices. Bob Copeland provides an ath5k fix that corrects a mistaken variable initialization. Felix Fietkau corrects some frame accounting for dropped frames in ath9k. Geert Uytterhoeven brings a Kconfig fix to indicate the DMA requirements for rt2x00. Larry Finger offers two rtlwifi fixes: one that properly initializes a callback; and, a scattered collection of Kconfig, Makefile, and EXPORT_SYMBOL changes that correct some build problems. Finally, Sujith Manoharan provides an ath9k fix to disable a feature on a specific hardware device. ==================== Signed-off-by:
