2015-08-10qlcnic: Add support to enable capability to extend minidump for iSCSIShahed Shaikh
In some cases it is required to capture minidump for iSCSI functions as part of default minidump collection process. To enable this, firmware exports it's capability and driver need to enable that capability by issuing a mailbox command. With this feature, firmware can provide additional iSCSI function's minidump with smaller minidump capture mask (0x1f). Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S.

2015-08-10net: fec: fix the race between xmit and bdp reclaiming pathKevin Hao
When we transmit a fragmented skb, we may run into a race like the following scenario (assume txq->cur_tx is next to txq->dirty_tx): cpu 0 cpu 1 fec_enet_txq_submit_skb reserve a bdp for the first fragment fec_enet_txq_submit_frag_skb update the bdp for the other fragment update txq->cur_tx fec_enet_tx_queue bdp = fec_enet_get_nextdesc(txq->dirty_tx, fep, queue_id); This bdp is the bdp reserved for the first segment. Given that this bdp BD_ENET_TX_READY bit is not set and txq->cur_tx is already pointed to a bdp beyond this one. We think this is a completed bdp and try to reclaim it. update the bdp for the first segment update txq->cur_tx So we shouldn't update the txq->cur_tx until all the update to the bdps used for fragments are performed. Also add the corresponding memory barrier to guarantee that the update to the bdps, dirty_tx and cur_tx performed in the proper order.

2015-08-09mlxsw: Simplify mlxsw_sx_port_xmit functionIdo Schimmel
Previously we only checked if the transmission queue is not full in the middle of the xmit function. This lead to complex logic due to the fact that sometimes we need to reallocate the headroom for our Tx header. Allow the switch driver to know if the transmission queue is not full before sending the packet and remove this complex logic.

2015-08-09mlxsw: Make system port to local port mapping explicitIdo Schimmel
System ports are unique identifiers in a multi-ASIC environment that represent all the available ports in the system. Local ports on the other hand, are unique only within the local ASIC. Since system port to local port mapping is not part of the HW-SW contract and since only single-ASIC configurations are currently supported, set an explicit 1:1 mapping by configuring the Switch System Port Record (SSPR) register.

2015-08-09net: dsa: mv88e6xxx: rework FDB getnext operationVivien Didelot
This commit adds a low level _mv88e6xxx_atu_getnext function and helpers to rewrite the mv88e6xxx_port_fdb_getnext operation. A mv88e6xxx_atu_entry structure is added for convenient access to the hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value. The previous implementation did not handle the eventual trunk mapping. If the related bit is set, then the ATU data register would contain the trunk ID, and not the port vector. Check this in the FDB getnext operation and do not handle it (yet). Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-09net: dsa: mv88e6xxx: extend fid maskVivien Didelot
The driver currently manages one FID per port (or bridge group), with a mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use. The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff; FID 0 means that multiple address databases are not being used). This patch changes the fid_mask for an fid_bitmap of 4096 bits. >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and bridge groups (a bridge group gets the FID of its first member). The remaining bits will be reserved for VLAN entries. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

IFLA_VXLAN_FLOWBASED is useless without IFLA_VXLAN_COLLECT_METADATA, so combine them into single IFLA_VXLAN_COLLECT_METADATA flag. 'flowbased' doesn't convey real meaning of the vxlan tunnel mode.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-08-05 This series contains updates to i40e, i40evf and e1000e. Anjali adds support for x772 devices to i40e and i40evf. With the added support, x772 supports offloading of the outer UDP transmit and receive checksum for tunneled packets. Also supports evicting ATR filters in the hardware, so update the driver with this new feature set. Raanan provides several fixes for e1000e, first rectifies the Energy Efficient Ethernet in Sx code so that it only applies to parts that actually support EEE in Sx. Fix whitespace and moved ICH8 related define to the proper context. Fixed the ASPM locking which was reported by Bjorn Helgaas. Fix a workaround implementation for systime which could experience a large non-linear increment of the systime value when checking for overflow. ==================== Signed-off-by: David S.

2015-08-06net/mlx5e: Take advantage of the light-weight netdev open/stopAchiad Shochat
Now that TIRs, TISs and flow tables are kept alive while the netdev is stopped (after executing ndo_stop()) we can do the following improvements: - Obsolete the active_vlans SW shadow. - Do not delete/add flow table rules upon ndo_stop/open. In addition to simplifying the flow, this change also fastens the ndo_open/close operations. - Obsolete synchronization of threads accessing the flow tables with the netdev stop/open threads.

2015-08-06net/mlx5e: Unify the RX flowAchiad Shochat
Generally an RX packet flows through the following objects: Flow table --> TIR --> RQT --> RQ Where: - TIR stands for "Transport Interface Receive", defining the RSS and LRO paramaters. - RQT stands for "RQ Table", implementing the RSS indirection table. - RQ stands for "Receive Queue" For flows that do not need LRO, nor RSS, the driver made a shortcut to the above RX flow by pointing to the RQ directly from the TIR, yielding this flow: Flow table --> TIR --> RQ In this commit we remove this shortcut by "inserting" a single-RQ RQT between the TIR and the RQ, i.e RX packets will reach the same RQ but will go through an RQT of size 1, pointing to just a single RQ. This way the RX traffic re-direction to/from the "Drop RQ" will be more uniform (AKA "one flow"), as it will involve only RQTs re-direction and no TIRs re-direction.
