This patch adds support for legacy SJA1000 CAN controllers on the ISA or PC-104 bus. The I/O port or memory address and the IRQ number must be specified via module parameters: insmod sja1000_isa.ko port=0x310,0x380 irq=7,11 for ISA devices using I/O ports or: insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 for memory mapped ISA devices. Indirect access via address and data port is supported as well: insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Here is a full list of the supported module parameters: port:I/O port number (array of ulong) mem:I/O memory address (array of ulong) indirect:Indirect access via address and data port (array of byte) irq:IRQ number (array of int) clk:External oscillator clock frequency (default=16000000 [16 MHz]) (array of int) cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF]) (array of byte) ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL]) (array of byte) Note: for clk, cdr, ocr, the first argument re-defines the default for all other devices, e.g.: insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \ clk=24000000,24000000 Signed-off-by:Wolfgang Grandegger <wg@grandegger.com> Tested-by:

Noticed by Stephen Rothwell: Today's linux-next build (x86_64 allmodconfig gcc-4.4.0) produced this warning: drivers/net/wan/dscc4.c: In function 'dscc4_rx_skb': drivers/net/wan/dscc4.c:670: warning: suggest parentheses around comparison in operand of '|' which actually points out a bug, I think. It is doing (x & (y | z)) != y | z when it probably means (x & (y | z)) != (y | z) Introduced by commit 5de3fcab ("WAN: bit and/or confusion"). Signed-off-by:

Here is a patch which fixes an issue observed when using TCP over IPv6 and AH from IPsec. When a connection gets closed the 4-way method and the last ACK from the server gets dropped, the subsequent FINs from the client do not get ACKed because tcp_v6_send_response does not set the transport header pointer. This causes ah6_output to try to allocate a lot of memory, which typically fails, so the ACKs never make it out of the stack. I have reproduced the problem on kernel 2.6.7, but after looking at the latest kernel it seems the problem is still there. Signed-off-by:

A0 revision ASIC has an erratum on the RQ desc cache on chip where the cache can become corrupted causing pkt buf writes to wrong locations. The s/w workaround is to post a dummy RQ desc in the ring every 32 descs, causing a flush of the cache. A0 parts are not production, but there are enough of these parts in the wild in test setups to warrant including workaround. A1 revision ASIC parts fix erratum. Signed-off-by:

Its hard to tell if vlans are dropping frames, since every frame given to vlan_???_start_xmit() functions is accounted as fully transmitted by lower device. We can test dev_queue_xmit() return values to properly account for dropped frames. Signed-off-by:

macvlan devices are currently not multi-queue capable. We can do that defining rtnl_link_ops method, get_tx_queues(), called from rtnl_create_link() This new method gets num_tx_queues/real_num_tx_queues from lower device. macvlan_get_tx_queues() is a copy of vlan_get_tx_queues(). Because macvlan_start_xmit() has to update netdev_queue stats only (and not dev->stats), I chose to change tx_errors/tx_aborted_errors accounting to tx_dropped, since netdev_queue structure doesnt define tx_errors / tx_aborted_errors.

The FCoE DDP in 82599 can be used for both FCoE initiator as well as FCoE target, depending on the indication of the exchange being the responder or originator in the F_CTL (frame control) field in the encapsulated Fiber Channel frame header (T10 Spec., FC-FS). For the initiator, OX_ID is used for FCoE DDP, where for the target RX_ID is used for FCoE DDP. Signed-off-by:

Yi Zou authored
This patch adds support for multiple transmit queues to the Fiber Channel over Ethernet (FCoE) feature found in 82599. Currently, FCoE has multiple Rx queues available, along with a redirection table, that helps distribute the I/O load across multiple CPUs based on the FC exchange ID. To make this the most effective, we need to provide the same layout of transmit queues to match receive. Particularly, when Data Center Bridging (DCB) is enabled, the designated traffic class for FCoE can have dedicated queues for just FCoE traffic, while not affecting any other type of traffic flow.

vlan_dev_hard_start_xmit() & vlan_dev_hwaccel_hard_start_xmit() select txqueue number 0, instead of using index provided by skb_get_queue_mapping(). This is not correct after commit 2e59af3d [vlan: multiqueue vlan device] because txq->tx_packets & txq->tx_bytes changes are performed on a single location, and not the right locking. Fix is to take the appropriate struct netdev_queue pointer Signed-off-by:

atm/br2684: netif_stop_queue() when atm device busy and netif_wake_queue() when we can send packets again. This patch removes the call to dev_kfree_skb() when the atm device is busy. Calling dev_kfree_skb() causes heavy packet loss then the device is under heavy load, the more correct behavior should be to stop the upper layers, then when the lower device can queue packets again wake the upper layers.
