2009-05-17ixgbe: Add infrastructure code for FCoE large send offload to 82599Yi Zou
This adds infrastructure code for FCoE Tx side offload feature to 82599, including Fiber Channel CRC calculation, auto insertion of the start of frame (SOF) and end of frame (EOF) of FCoE packets, and large send by FCoE Sequence Offload (FSO).

2009-05-17ixgbe: Add FCoE feature code to 82599Yi Zou
This adds the FCoE feature code ixgbe_fcoe.c to 82599. For a start, this patch only adds ixgbe_configure_fcoe() to configure related register for FCoE to 82599. In patches that follow, I will be adding more functions to ixgbe_fcoe.c to add support of FCoE offload features to 82599.

2009-05-17ixgbe: Add FCoE feature header to 82599Yi Zou
This adds the FCoE feature header ixgbe_fcoe.h to 82599. This header includes the defines and structures required by the ixgbe driver to support various offload features in 82599 for Fiber Channel over Ethernet (FCoE). These offloads features include Fiber Channel CRC calculation, FCoE SOF/EOF auto insertion, FCoE Sequence Offload (FSO) for large send, and Direct Data Placement (DDP) for large receive.

2009-05-09tun: add tun_flags, owner, group attributes in sysfsDavid Woodhouse
This patch adds three attribute files in /sys/class/net/$dev/ for tun devices; allowing userspace to obtain the information which TUNGETIFF offers, and more, but without having to attach to the device in question (which may not be possible if it's in use). It also fixes a bug which has been present in the TUNGETIFF ioctl since its inception, where it would never set IFF_TUN or IFF_TAP according to the device type. (Look carefully at the code which I remove from tun_get_iff() and how the new tun_flags() helper is subtly different).

after the recent changes to wired drivers to use only netif_carrier_off the driver can have outstanding tx work to complete that will never complete once link is down. Since the intel hardware will hold this tx work forever, the driver notices a tx timeout condition internally and might try to instigate printk and reset of the part with a netif_stop_queue, which doesn't work because link is down.

2009-05-07ixgbe: fix failing to log fan failuresDon Skidmore
We weren't logging the 82598AT fan failure if it occurred before (ixgbe_open) as we hadn't sent up to catch the interrupt that event caused. This patch checks for this failure in: ixgbe_probe - So we can log the failure asap. We check right after we set up the adapter->flags, which is when we know that we have a fan. ixgbe_up_complete - To catch failures that may have happened between probe and when we set up the interrupt that would normally detect the fan failure. To enable all of this we need to initialize the adapter flag with IXGBE_FLAG_FAN_FAIL_CAPABLE when the NIC contained a fan.

2009-05-06bnx2: Fix panic in bnx2_poll_work().Michael Chan
Add barrier() to bnx2_get_hw_{tx|rx}_cons() to fix this issue: http://bugzilla.kernel.org/show_bug.cgi?id=12698 This issue was reported by multiple i386 users. Without barrier(), the compiled code looks like the following where %eax contains the address of the tx_cons or rx_cons in the DMA status block. The status block contents can change between the cmpb and the movzwl instruction. The driver would crash if the value was not 0xff during the cmpb instruction, but changed to 0xff during the movzwl instruction. 6828: 80 38 ff cmpb $0xff,(%eax) 682b: 0f b7 10 movzwl (%eax),%edx With the added barrier(), the compiled code now looks correct: 683d: 0f b7 10 movzwl (%eax),%edx 6840: 0f b6 c2 movzbl %dl,%eax 6843: 3d ff 00 00 00 cmp $0xff,%eax Thanks to Pascal de Bruijn <pmjdebruijn@pcode.nl> for reporting the problem and Holger Noefer <hnoefer@pironet-ndh.com> for patiently testing test patches for us.
