2015-02-23samples/pktgen: Use bash as interpreterBen Hutchings8-8/+8
These scripts use the non-POSIX 'function' and 'local' keywords so they won't work with every /bin/sh. We could drop 'function' as it is a no-op, but 'local' makes for cleaner scripts.

Sathya Perla says: ==================== be2net: patch set Hi Dave, the following patch set reduces code duplication in probe/pci-resume/eeh-resume and remove/pci-suspend/eeh-error and UE-error detect/recovery paths. New helper routines have been introduced for this purpose. Pls apply this set to the net-next tree. Thanks! Patch 1 refactors the alloc/free code of adapter struct's fields into a new set of helper routines -- be_drv_init/cleanup(). Patch 2 gets rid of the be_get_initial_config() routine as be_get_config() is the place holder for related code. Patch 3 introduces a new helper routine be_func_init() to execute the initialization code used in probe/pci-resume/eeh-resume to remove code duplication. Patch 4 introduces a wrapper for scheduling/canceling error detection task on similar lines to the be_worker task. Patch 5 refactors UE error detection and recovery code on similar lines to EEH code. Cleaning up resources is done in the error detection routine followed by error recovery. Patch 6 gets rid of the lancer_test_and_set_rdy_state() routine as the same code now available in be_func_init(). Patch 7 creates a new helper routine be_resume() for all the common code in be_probe(), be_pci_resume() and be_eeh_resume(), to reduce code duplication. Patch 8 creates a new helper routine be_cleanup() for all the common cleanup code duplicated in the suspend/EEH err detection paths. Patch 9 moves be_func_init() inside be_setup() as everytime be_setup() is called, the driver will have to wait for the function/FW to be be initialized. ==================== Signed-off-by: David S.

2015-02-23be2net: remove code duplication relating to Lancer reset sequenceSathya Perla2-117/+55
The steps needed for Lancer's reset/initialization sequence are: a) wait for SLIPORT_STAUS RDY bit to be set b) set the SLIPORT_CONTROL IP bit c) repeat step "a" The code needed for this sequence is already covered by the be_func_init() routine (with minor modifications.) So, get rid of the lancer_test_and_set_rdy_state() and lancer_provisioning_error() routines that unnecessarily duplicate this code.

2015-02-23be2net: refactor error detect/recovery functionKalesh AP1-14/+17
Currently when an error is detected, the queue resources are being cleaned up in the recovery routine. The resources are better cleaned up in the error detection routine itself (similar to EEH code.) So, this patch re-factors error processing logic to follow the following sequence: - check if there is an error in adapter - if error, - cleanup resources - attempt recovery The patch renames lancer_recover_func() to be_err_recover() as this routine will be used in the future for error recovery on Skyhawk too.

2015-02-23be2net: move adapter fields alloc/free code to new routinesSathya Perla1-213/+195
The members of be_adapter struct were being allocated in two separate routines -- be_ctrl_init() and be_stats_init(). Also, some other members were allocated elsewhere. This patch moves the alloc/free code into be_drv_init/cleanup() routines. The be_pci_map_bars() routine that was called from be_ctrl_init() is now called directly from be_probe(). The new routine be_drv_init() will now be the place-holder for allocating memory for any new be_adapter{} members in the future. Some routines needed to be moved to provide forward definitions for their calls.

2015-02-22bridge: add vlan info to bridge setlink and dellink notification messagesRoopa Prabhu1-22/+24
vlan add/deletes are not notified to userspace today. This patch adds vlan info to bridge newlink/dellink notifications generated from the bridge driver. Notifications use the RTEXT_FILTER_BRVLAN_COMPRESSED flag to compress vlans into ranges whereever applicable. The size calculations does not take ranges into account for simplicity. This has the potential for allocating a larger skb than required. There is an existing inconsistency with bridge NEWLINK and DELLINK change notifications. Both generate NEWLINK notifications. Since its always a NEWLINK notification, this patch includes all vlans the port belongs to in the notification. The NEWLINK and DELLINK request messages however only include the vlans to be added and deleted. Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S.

The WRB header is setup by wrb_fill_hdr() routine. This routine currently gets some of the WRB params as args and figures out rest of the WRB params by looking at various fields in skb (like gso, checksum, vlan-tag etc). All these params could instead be retrieved from the skb into a structure and passed to this routine. This separates wrb_fill_hdr() to only provide chip-specific code to fill the WRB. This also makes it simple to support chips with different WRB formats. Signed-off-by: Sriharsha Basavapatna <sriharsha.basavapatna@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Andrew Lunn says: ==================== Indirect phy access for mv88e6171 These two patches allow the mv88e6171 driver to access the port phys using indirect addressing. Depending on pin strapping, the switch either uses a single address on the host MDIO bus, requiring the port phys are accessed indirectly, or the switch uses a number of addresses on the host bus and the phys can be directly accessed. The 370RD, the first supported platform to use the 6171 uses multiple addresses, so this indirect mode was not required. However the WRT1900AC has the switch configured to use a single address, and so indirect access is needed. The mv88e6352 already has all the needed code. Refactor it into the shared mv88e6xxx and then use it in the mv88e6171 driver. Tested on the 370RD and WRT1900AC. It would be good if Guenter Roeck could test on his platform to ensure i've not broken anything for the mv88e6352. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
