git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, ixgbevf, ixgbe and igb. Don provides an ixgbevf patch to add DCB configuration into the queue setup so that we won't have to allocate queues in a separate place when enabling DCB. Guenter Roeck provides 2 patches for ixgbe to simplify the code by attaching hwmon sysfs attributes to hwmon device instead of PCI device. Also fix an issues where the temperature sensor attribute index was being started with the value 0 and not 1 as per the hwmon API. Carolyn provides igb patches to fix queue allocation method to accommodate changes during runtime. This includes changing how the driver initializes MSIx and checks for MSIx configuration to make it easier to reconfigure the device when queue changes happen at runtime. Neerav and Shannon fixes i40e debugfs commands that dump hex information by using print_hex_dump(). Shannon provides several i40e fixes which include the prevention of null pointer exception in the dump descriptor by checking that rings were allocated before trying to reference them. Fixed up a couple of scanfs to accept various base numbers instead of silently requiring hex. Anjali fixes up i40e where the incorrect defines were being used for misc interrupts. Alan Cox provides a fix for i40e where we assume that the resulting buffer is zero terminated when we then re-use it. The sscanf is limited to 512 bytes but needs to be 511 to allow for a terminator. Stephen Hemminger fixes i40e by making local functions static and removes unused code (i40e_aq_add/remove_vlan() functions). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-12-17igb: Change to use statically allocated array for MSIx entriesCarolyn Wyborny

2013-12-17igb: Fix queue allocation method to accommodate changing during runtimeCarolyn Wyborny
When changing number of queues using ethtool's set_channels during runtime, a queue allocation could fail, which can leave the device in a down state. In order to preserve the usability of the device in this scenario, this patch changes the driver to allocate the number of queues only if they have not been allocated already. The first allocation is then done for the max number of queues, which is the default queues for this driver. With this change, queue quantity changes are not subject to queue allocation failures.

2013-12-17ixgbe: Convert to use devm_hwmon_device_register_with_groupsGuenter Roeck
Simplify the code. Attach hwmon sysfs attributes to hwmon device instead of pci device. Avoid race conditions caused by attributes being created after hwmon device registration. Implicitly (through hwmon API) add mandatory 'name' sysfs attribute. Other cleanup: Instead of allocating memory for hwmon attributes, move attributes and all other hwmon related data into struct hwmon_buff and allocate the entire structure using devm_kzalloc. Check return value from calls to igb_add_hwmon_attr() one by one instead of logically combining them all together.

2013-12-18bna: Firmware Patch SimplificationRasesh Mody
This patch includes change to enable firmware patch simplication feature. This feature is targeted to address the requirement to have independent patch release for firmware. Prior to the 3.2.3.0 firmware, releasing a patch fix for firmware would require changes to bna driver, to use new firmware images. However with these changes, if the new firmware is flashed on to the Adapter, the driver will use the new firmware after checking the patch release byte in the firmware version.

2013-12-18bna: Handle the TX Setup FailuresRasesh Mody
Change details: - When bnad_setup_tx() returns NULL, the error is NOT returned to the caller. The caller will incorrectly assume success. So Return ENOMEM when bna_tx_create() fails. - If bnad_tx_msix_register() fails, call bna_tx_destroy() to free tx & to NULL the bnad reference to tcb.

2013-12-18bna: Add NULL Check Before Dereferencing TCBRasesh Mody
Currently we already check to see whether the BNAD_TXQ_TX_STARTED cleared. But if the tcb structure which contains this flag is also already freed by that time, we would dereference the NULL pointer. This patch is to check tcb for NULL pointer, before dereferencing it. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-12-18bna: Enable Multi Buffer RXRasesh Mody
The CT2 HW supports multi-buffer Rx. This patch provides the necessary changes for bnad to use multi-buffer Rx feature. For BNAD, multi-buffer Rx is by default enabled when MTU is > 4096. For >4096 MTU, q0 data/large buffers are of 2048 size. As the resource requirements of multi-buffer Rx are different new Rx needs to be created to use this feature. ASIC posts multiple completions if frame exceeds buffer size. The last completion is marked with EOP flag. - Separate HQ and DQ enums for resource allocations and configurations. - rx_config and rxq structure changes to pass the correct info from bnad. - DQ depth need not be same as HQ depth. So CQ depth is adjusted accordingly. - Rx CFG frame size is taken from configured MTU. - Rx q0 buffer size is configured from bnad s rx_config when multi-buffer is enabled. - Poll for entire frame completion. - Once EOP completion is received gather the number of vectors used by the frame to submit it to the stack. - Changed MTU to frame size wherever necessary.

2013-12-18bna: RX Filter EnhancementsRasesh Mody
Change Details: - Added bna_rx_ucast_listset() for synchronous ucast listadd operation. - Clear mac->handle before adding it to free_q. - bnad_set_rx_mode() rewritten. bnad_set_rx_mode() adds the MACs in uc_list to UCAM. If it exceeds the max supported, DEFAULT mode is turned on. If MCAM limit is exceeded, ALLMULTI mode is turned on. - Clear CF flags, check for the new mode and reprogram the Rx approach. - Added bnad_set_rx_ucast_fltr() and bnad_set_rx_mcast_fltr(). - Check for IFF_PROMISC to set the correct mode.

2013-12-18bna: Fix Filter Add DelRasesh Mody
Change Details: - bna_rx_mcast_listset() API first looks at free_q only and not at other pending Qs rendering it non-deterministic of giving an upper limit. Modify bna_rx_mcast_listset() implementation to not use only half of the limit. - Allocate and initialize queue for deleting - Segregate the adding and deleting process by using separate queues. - The filter framework in bna does not let adding addresses to its max capacity due to asynchronous operations involved.
