2009-09-03ixgbe: Add support for using FCoE DDP in 82599 as FCoE targetsYi Zou
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.

2009-09-03ixgbe: Add support for multiple Tx queues for FCoE in 82599Yi Zou
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.

when we can send packets again. This patch removes the call to dev_kfree_skb() when the atm device is busy.

2009-09-02NET: Fix possible corruption in bpqether driverRalf Baechle
The bpq ether driver is modifying the data art of the skb by first dropping the KISS byte (a command byte for the radio) then prepending the length + 4 of the remaining AX.25 packet to be transmitted as a little endian 16-bit number. If the high byte of the length has a different value than the dropped KISS byte users of clones of the skb may observe this as corruption. This was observed with by running listen(8) -a which uses a packet socket which clones transmit packets. The corruption will then typically be displayed for as a KISS "TX Delay" command for AX.25 packets in the range of 252..508 bytes or any other KISS command for yet larger packets. Fixed by using skb_cow to create a private copy should the skb be cloned. Using skb_cow also allows us to cleanup the old logic to ensure sufficient headroom in the skb. While at it, replace a return of 0 from bpq_xmit with the proper constant NETDEV_TX_OK which is now being used everywhere else in this function. Affected: all 2.2, 2.4 and 2.6 kernels.

2009-09-02tcp: replace hard coded GFP_KERNEL with sk_allocationWu Fengguang
This fixed a lockdep warning which appeared when doing stress memory tests over NFS: inconsistent {RECLAIM_FS-ON-W} -> {IN-RECLAIM_FS-W} usage. page reclaim => nfs_writepage => tcp_sendmsg => lock sk_lock mount_root => nfs_root_data => tcp_close => lock sk_lock => tcp_send_fin => alloc_skb_fclone => page reclaim David raised a concern that if the allocation fails in tcp_send_fin(), and it's GFP_ATOMIC, we are going to yield() (which sleeps) and loop endlessly waiting for the allocation to succeed. But fact is, the original GFP_KERNEL also sleeps. GFP_ATOMIC+yield() looks weird, but it is no worse the implicit sleep inside GFP_KERNEL. Both could loop endlessly under memory pressure.

2009-09-02net/ethtool: Add support for the ethtool feature to flash firmware image ↵Ajit Khaparde
from a specified file. This patch adds support to flash a firmware image to a device using ethtool. The driver gets the filename of the firmware image and flashes the image using the request firmware path. The region "on the chip" to be flashed can be specified by an option. It is upto the device driver to enumerate the region number passed by ethtool, to the region to be flashed. The default behavior is to flash all the regions on the chip.

2009-09-02ip: Report qdisc packet dropsEric Dumazet
Christoph Lameter pointed out that packet drops at qdisc level where not accounted in SNMP counters. Only if application sets IP_RECVERR, drops are reported to user (-ENOBUFS errors) and SNMP counters updated. IP_RECVERR is used to enable extended reliable error message passing, but these are not needed to update system wide SNMP stats. This patch changes things a bit to allow SNMP counters to be updated, regardless of IP_RECVERR being set or not on the socket. Example after an UDP tx flood # netstat -s ... IP: 1487048 outgoing packets dropped ... Udp: ... SndbufErrors: 1487048 send() syscalls, do however still return an OK status, to not break applications. Note : send() manual page explicitly says for -ENOBUFS error : "The output queue for a network interface was full. This generally indicates that the interface has stopped sending, but may be caused by transient congestion. (Normally, this does not occur in Linux. Packets are just silently dropped when a device queue overflows.) " This is not true for IP_RECVERR enabled sockets : a send() syscall that hit a qdisc drop returns an ENOBUFS error.

2009-09-02net: drop_monitor: make last_rx timestamp privateNeil Horman
It was recently pointed out to me that the last_rx field of the net_device structure wasn't updated regularly. In fact only the bonding driver really uses it currently. Since the drop_monitor code relies on the last_rx field to detect drops on recevie in hardware, We need to find a more reliable way to rate limit our drop checks (so that we don't check for drops on every frame recevied, which would be inefficient. This patch makes a last_rx timestamp that is private to the drop monitor code and is updated for every device that we track. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2009-09-02cfg80211: fix looping soft lockup in find_ie()Bob Copeland
The find_ie() function uses a size_t for the len parameter, and directly uses len as a loop variable. If any received packets are malformed, it is possible for the decrease of len to overflow, and since the result is unsigned, the loop will not terminate. Change it to a signed int so the loop conditional works for negative values. This fixes the following soft lockup: [38573.102007] BUG: soft lockup - CPU#0 stuck for 61s!

2009-09-02tg3: Add MDIO bus address assignmentsMatt Carlson
The 5717 is a dual port chip that has a shared MDIO bus design. While it is impossible for one function to interface with the wrong phy, that function still needs to know which MDIO bus address to use when interfacing with its own phy. This patch adds code to determine which MDIO bus address to use. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Reviewed-by: Benjamin Li <benli@broadcom.com> Signed-off-by: David S.

2009-09-02tg3: Assign rx ret producer indexes by vectorMatt Carlson
When RSS is enabled, the status block format changes slightly. The "rx_jumbo_consumer", "reserved", and "rx_mini_consumer" members get mapped to the other three rx return ring producer indexes. This patch introduces a new per-interrupt member which identifies which location in the status block a particular vector should look for return ring updates.

2009-09-02tg3: Adjust RSS ring allocation strategiesMatt Carlson
When multivector RSS is enabled, the first interrupt vector is only used to report link interrupts and error conditions. This patch changes the code so that rx and tx ring resources are not allocated for this vector.
