2016-04-06mwifiex: advertise low priority scan featureAmitkumar Karwar1-0/+1
Low priority scan handling code which delays or aborts scan operation based on Tx traffic is removed recently. The reason is firmware already takes care of it in our new feature scan channel gap. Hence we should advertise low priority scan support to cfg80211. This patch fixes a problem in which OBSS scan request from wpa_supplicant was being rejected by cfg80211.

2016-04-06rt2x00usb: Use usb anchor to manage URBVishal Thanki3-2/+25
With current driver, it is observed that a URB is not completed while the USB disconnect is initiated. Due to that, the URB completion handler is trying to access the resource which was freed as a part of USB disconnect. Managing the URBs with anchor will make sure that all the URBs are handled gracefully before device gets disconnected.

2016-04-06rtlwifi: rtl8723be: Add antenna select module parameterLarry Finger3-0/+11
A number of new laptops have been delivered with only a single antenna. In principle, this is OK; however, a problem arises when the on-board EEPROM is programmed to use the other antenna connection. The option of opening the computer and moving the connector is not always possible as it will void the warranty in some cases. In addition, this solution breaks the Windows driver when the box dual boots Linux and Windows. A fix involving a new module parameter has been developed. This commit adds the new parameter and implements the changes needed for the driver.

2016-04-05net/core/dev: Warn on a too-short GRO frameAaron Conole1-0/+2
When signaling that a GRO frame is ready to be processed, the network stack correctly checks length and aborts processing when a frame is less than 14 bytes. However, such a condition is really indicative of a broken driver, and should be loudly signaled, rather than silently dropped as the case is today. Convert the condition to use net_warn_ratelimited() to ensure the stack loudly complains about such broken drivers. Signed-off-by: Aaron Conole <[email protected]> Signed-off-by: David S.

Allow the VNIC driver to provide descriptors containing L2/L3/L4 headers to firmware. This feature is needed for greater hardware compatibility and enablement of checksum and TCP offloading features. A new function is included for the hypervisor call, H_SEND_SUBCRQ_INDIRECT, allowing a DMA-mapped array of SCRQ descriptor elements to be sent to the VNIC server. These additions will help fully enable checksum offloading as well as other features as they are included later.

2016-04-05net: bcmgenet: cleanup for dmadesc_set()Petri Gynther1-1/+1
dmadesc_set() is used for setting the Tx buffer DMA address, length, and status bits on a Tx ring descriptor when a frame is being Tx'ed. Always set the Tx buffer DMA address first, before updating the length and status bits, i.e. giving the Tx descriptor to the hardware. The reason this is a cleanup rather than a fix is that the hardware won't transmit anything from a Tx ring until the TDMA producer index has been incremented. As long as the dmadesc_set() writes complete before the TDMA producer index write, life is good.

Enable peeking at UDP datagrams at the offset specified with socket option SOL_SOCKET/SO_PEEK_OFF. Peek at any datagram in the queue, up to the end of the given datagram. Implement the SO_PEEK_OFF semantics introduced in commit ef64a54f6e55 ("sock: Introduce the SO_PEEK_OFF sock option"). Increase the offset on peek, decrease it on regular reads. When peeking, always checksum the packet immediately, to avoid recomputation on subsequent peeks and final read. The socket lock is not held for the duration of udp_recvmsg, so peek and read operations can run concurrently. Only the last store to sk_peek_off is preserved.

Stefan converts dev_close() to ndo_stop() for ethtool offline self test, since dev_close() causes IFF_UP to be cleared which will remove the interface routes and addresses. Alex bumps up the size of the transmit data buffer to 12K rather than 8K, which provides a gain in throughput and a reduction in overhead for putting together the frame. Fixed an issue in the polling routines where we were using bitwise operators to avoid the side effects of the logical operators. Then added support for bulk transmit clean for skbs. Jesse fixed a sparse issue in the type casting in the transmit code and fixed i40e_aq_set_phy_debug() to use i40e_status as a return code. Catherine cleans up duplicated code. Shannon fixed the cleaning up of the interrupt handling to clean up the IRQs only if we actually got them set up. Also fixed up the error scenarios where we were trying to remove a non-existent timer or worktask, which causes the kernel heartburn. Mitch changes the notification of resets to the reset interrupt handler, instead of the actual reset initiation code. This allows the VFs to get properly notified for all resets, including resets initiated by different PFs on the same physical device. Also moved the clearing of VFLR bit after reset processing, instead of before which could lead to double resets on VF init. Fixed code comment to match the actual function name. ==================== Signed-off-by: David S. Miller <[email protected]>

Fix a kernel panic that occurs during surprise removal. Clear the interface queue counts upon fm10k_init_msix_capability failure. This prevents further code (fm10k_update_stats etc.) from attempting to access unallocated queue vector or ring memory.

2016-04-05fm10k: add helper functions to set strings and data for ethtool statsJacob Keller1-81/+83
Reduce duplicate code and the amount of indentation by adding fm10k_add_stat_strings and fm10k_add_ethtool_stats functions which help add fm10k_stat structures to the ethtool stats callbacks. This helps increase ease of use for future stat additions, and increases code readability. Skip handling of the per-queue stats as these will be reworked in a following patch.

2016-04-05fm10k: free MBX IRQ before clearing interrupt schemeJacob Keller1-2/+2
During fm10k_io_error_detected we were clearing the interrupt scheme before we freed the MBX IRQ. This causes a kernel panic because the MBX IRQ are assigned after MSI-X initialization. Clearing the interrupt scheme results in removing the MSI-X entry table. Fix this by freeing the MBX IRQ before we clear the interrupt scheme, as we do elsewhere in the driver.

2016-04-05fm10k: print error message when stop_hw failsJacob Keller1-1/+4
fm10k_stop_hw_generic calls fm10k_disable_queues_generic, which may return an error code indicating that the queues were not stopped within the time limit. Notify the user by displaying a message in the kernel message ring, in a similar way to how we notify the user when reset_hw fails. There isn't much we can do to recover from this error, so currently nothing else is done.
