2015-02-07be2net: avoid unncessary swapping of fields in eth_tx_wrbSathya Perla
The 32-bit fields of a tx-wrb are little endian. The driver is currently using be_dws_le_to_cpu() routine to swap (cpu to le) all the fields of a tx-wrb. So, the rsvd field is also unnecessarily swapped. This patch fixes this by individually swapping the required fields. Also, the type of the fields in eth_tx_wrb{} is now changed to __le32 from u32 to avoid sparse warnings. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2015-02-07be2net: process port misconfig async eventVasundhara Volam
This patch adds support for processing the port misconfigure async event generated by the FW. This event is generated typically when an optical module is incorrectly installed or is faulty. This patch also moves the port_name field to the adapter struct for logging the event. As the be_cmd_query_port_name() call is now moved to be_get_config(), it is modified to use the mailbox instead of MCCQ Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2015-02-07be2net: refactor be_set_rx_mode() and be_vid_config() for readabilitySathya Perla
This patch re-factors the filter setting (uc-list, mc-list, promisc, vlan) code in be_set_rx_mode() and be_vid_config() to make it more readable and reduce code duplication. This patch adds a separate field to track the state/mode of filtering, along with moving all the filtering related fields to one place in be be_adapter structure.

2015-02-07be2net: remove duplicate code in be_cmd_rx_filter()Sathya Perla
This patch passes BE_IF_FLAGS_XXX flags to be_cmd_rx_filter() routine instead of the IFF_XXX flags. Doing this gets rid of the code to convert the IFF_XXX flags to the BE_IF_FLAGS_XXX used by the FW cmd. The patch also removes code for setting if_flags_mask that was duplicated for each filter mode.

2015-02-07be2net: use offset based FW flashing for Skyhawk chipVasundhara Volam
While sending FW update cmds to the FW, the driver specifies the "type" of each component that needs to be flashed. The FW then picks the offset in the flash area at which the componnet is to be flashed. This doesn't work when new components that the current FW doesn't recognize, need to be flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein the "offset" of the component in the flash area can be specified instead of the "type". This patch uses the "offset" based FW-update mechanism and only when it fails, it fallsback to the old "type" based update.

2015-02-07be2net: refactor code that checks flash file compatibilityVasundhara Volam
This patch re-factors the code that checks for flash file compatibility with the chip type, for better readability, as follows: - be_get_ufi_type() returns the UFI type from the flash file - be_check_ufi_compatibility() checks if the UFI type is compatible with the adapter/chip that is being flashed Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-02-05 This series contains updates to fm10k, ixgbe and ixgbevf. Matthew fixes an issue where fm10k does not properly drop the upper-most four bits on of the VLAN ID due to type promotion, so resolve the issue by not masking off the bits, but by throwing an error if the VLAN ID is out-of-bounds. Then cleans up two cases where variables were not being used, but were being set, so just remove the unused variables. Don cleans up sparse errors in the x550 family file for ixgbe. Fixed up a redundant setting of the default value for set_rxpba, which was done twice accidentally. Cleaned up the probe routine to remove a redundant attempt to identify the PHY, which could lead to a panic on x550. Added support for VXLAN receive checksum offload in x550 hardware. Added the Ethertype Anti-spoofing feature for affected devices. Emil enables ixgbe and ixgbevf to allow multiple queues in SRIOV mode. Adds RSS support for x550 per VF. Fixed up a couple of issues introduced in commit 2b509c0cd292 ("ixgbe: cleanup ixgbe_ndo_set_vf_vlan"), fixed setting of the VLAN inside ixgbe_enable_port_vlan() and disable the "hide VLAN" bit in PFQDE when port VLAN is disabled. Cleaned up the setting of vlan_features by enabling all features at once. Fixed the ordering of the shutdown patch so that we attempt to shutdown the rings more gracefully. We shutdown the main Rx filter in the case of Rx and we set the carrier_off state in the case of Tx so that packets stop being delivered from outside the driver. Then we shutdown interrupts and NAPI, then finally stop the rings from performing DMA and clean them. Added code to allow for Tx hang checking to provide more robust debug info in the event of a transmit unit hang in ixgbevf. Cleaned up ixgbevf logic dealing with link up/down by breaking down the link detection and up/down events into separate functions, similar to how these events are handled in other drivers. Combined the ixgbevf reset and watchdog tasks into a single task so that we can avoid multiple schedules of the reset task when we have a reset event needed due to either the mailbox going down or transmit packets being present on a link down. v2: Fixed up patch #03 of the series to remove the variable type change based on feedback from David Laight ==================== Signed-off-by: David S.

2015-02-07amd-xgbe: Check per channel DMA interrupt use in main ISRLendacky, Thomas
When using per channel DMA interrupts the transmit interrupt (TI) and the receive interrupt (RI) are masked off so as to not generate an interrupt to the main ISR. However, should another interrupt fire for the DMA channel that is handled by the main ISR the TI/RI bits can still be set. This will cause the wrong and uninitialized napi structure to be used causing a panic. Add a check to be sure per channel DMA interrupts are not enabled before acting on those bit flags.

2015-02-07net: dsa: bcm_sf2: implement GPHY power downFlorian Fainelli
Implement the power on/off recommended procedure for the Single GPHY we have on our Starfighter 2 switch. In order to make sure we get proper LED link/activity signaling during suspend, switch the link indication from the Switch/MAC to the PHY. Finally, since the GPHY needs to be reset to be put in low power mode, we will loose any context applied to it: workarounds, EEE etc.. so we need to call phy_init_hw() to get our fixups re-applied successfully.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next NFC: 3.20 second pull request This is the second NFC pull request for 3.20. It brings: - NCI NFCEE (NFC Execution Environment, typically an embedded or external secure element) discovery and enabling/disabling support. In order to communicate with an NFCEE, we also added NCI's logical connections support to the NCI stack. - HCI over NCI protocol support. Some secure elements only understand HCI and thus we need to send them HCI frames when they're part of an NCI chipset. - NFC_EVT_TRANSACTION userspace API addition. Whenever an application running on a secure element needs to notify its host counterpart, we send an NFC_EVENT_SE_TRANSACTION event to userspace through the NFC netlink socket. - Secure element and HCI transaction event support for the st21nfcb chipset.

2015-02-07serial: 8250: Fix UART_BUG_TXEN workaroundPeter Hurley
UARTs which do not trigger THRE interrupt if the fifo is already empty when the interrupt is enabled need tx primed manually. These UARTs are identified by the UART_BUG_TXEN flag to enable the required workaround. However, the current workaround is broken; if the fifo is already empty but the shifter is still transmitting, then serial8250_tx_chars() will not be called but no further THRE interrupt will occur, and tx will stall. The appropriate check is for fifo empty (THRE), not transmitter empty (TEMT).

A few redundant switch cases as well as a redundant if/else within one of the cases was consolidated to a single call. The cases are intentionally retained for documentation purposes. case WIFI_REASSOCREQ,WIFI_PROBEREQ,WIFI_BEACON,WIFI_ACTION all have the same effect - notably the also for WIFI_PROBEREQ where the if/else is executing the same function. These redundant cases could all be dropped and consolidated into the default but probably it is better for documentation/readability to leave them in the switch/case explicitly.
