2009-12-18gianfar: Fix stats supportSandeep Gopalpet
This patch updates the per rx/tx queue stats. To update the per rx queue stats a new structure has been introduced rx_q_stats. The per tx queue stats are updated via the netdev_queue structure itself. Note that we update only the tx_packtes, tx_bytes, rx_packets, rx_bytes and rx_dropped stats on a per queue basis.

2009-12-18can/at91: don't check platform_get_irq's return value against zeroUwe Kleine-König
platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use (int)irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

2009-12-18bnx2: reset_task is crashing the kernel. Fixing it.Breno Leitao
If bnx2 schedules a reset via the reset_task, e.g., due to a TX timeout, it's possible for the NIC to be disabled with packets pending for transmit. In this case, napi_disable will loop forever, eventually crashing the kernel. This patch moves the disable of the device to after the napi_disable call.

2009-12-18e100: Fix broken cbs accounting due to missing memset.Roger Oksanen
Alan Stern noticed that e100 caused slab corruption. commit 98468efddb101f8a29af974101c17ba513b07be1 changed the allocation of cbs to use dma pools that don't return zeroed memory, especially the cb->status field used to track which cb to clean, causing (the visible) double freeing of skbs and a wrong free cbs count. Now the cbs are explicitly zeroed at allocation time.

2009-12-15ixgbe: allow tx of pre-formatted vlan tagged packetsGurucharan Shetty
When the 82598 is fed 802.1q packets, it chokes with an error of the form: ixgbe: eth0: ixgbe_tx_csum: partial checksum but proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out with the correct hardware checksum. This patch is a clone of a previously submitted patch by Arthur Jones <ajones@riverbed.com> for igb (Commit - fa4a7ef36ec834fee1719636b30d2f28f4cb0166).

Modified patch with Dave's comments to replace mdelay with proper msleep. Fix 82598 copper link issue, where the phy prematurely indicates link before it is ready to process packets. The new function looks for phy link and indicates that, when it is available. If phy is not ready within few seconds of MAC indicating link, the function will return failure which translates to link down indication.

2009-12-13can: Fix data length code handling in rx pathOliver Hartkopp
A valid CAN dataframe can have a data length code (DLC) of 0 .. 8 data bytes. When reading the CAN controllers register the 4-bit value may contain values from 0 .. 15 which may exceed the reserved space in the socket buffer! The ISO 11898-1 Chapter 8.4.2.3 (DLC field) says that register values > 8 should be reduced to 8 without any error reporting or frame drop. This patch introduces a new helper macro to cast a given 4-bit data length code (dlc) to __u8 and ensure the DLC value to be max. 8 bytes. The different handlings in the rx path of the CAN netdevice drivers are fixed.

2009-12-11tty: moxa: split open lockAlan Cox
moxa_openlock is used for several situations where we want to handle the case of an ioctl that crosses many ports (not just the open tty), and also cases where an open races a deinit (eg a pci unplug) and we hangup a port before we can cope with that. The non open race cases can use the moxa_lock spinlock. This simplifies sorting out the remaining mess.
