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. Also fixed the error recovery function to take care of these changes Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: Kalesh AP <kalesh.purayil@emulex.com> Signed-off-by: David S.

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.

2015-02-20be2net: Refactor wrb_fill_hdr() routineSriharsha Basavapatna2-39/+99
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>

Commit a7854487cd7128a30a7f4f5259de9f67d5efb95f: md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write. Causes an RCW cycle to be forced even when the array is degraded. A degraded array cannot support RCW as that requires reading all data blocks, and one may be missing. Forcing an RCW when it is not possible causes a live-lock and the code spins, repeatedly deciding to do something that cannot succeed. So change the condition to only force RCW on non-degraded arrays.

While reporting the (refreshed) list of modules on automatic updates we may hit the page boundary of the output console and cause a stop if pagination is enabled. However, gdb does not accept user input while running over the breakpoint handler. So we get stuck, and the user is forced to interrupt gdb.
