2009-06-03e1000e: workaround a Tx hang on 82577/82578Bruce Allan
With bi-directional stress traffic, the receiver could hang causing the hardware to stop and a "Detected Tx Unit Hang" message dumped to the system logfile. Temporarily workaround this issue by disabling Tx flow control by default. The issue is currently being investigated and a follow-on patch will be provided to revert this when it is resolved.

2009-06-03e1000e: add support for 82577/82578 GbE LOM partsBruce Allan
This patch provides support for the next generation Intel desktop and mobile gigabit ethernet LOM adapters. These adapters are the follow-on parts to the LOMs tied to the prior ICH chipsets and are comprised of a MAC in the PCH chipset and an external PHY (82577 for mobile and 82578 for desktop versions). New features consist of PHY wakeup to save power by completely turning off the MAC while in Sx state, and 4K jumbo frames.

2009-06-03e1000e: correct flow control thresholdsBruce Allan
The flow control thresholds, i.e. high and low watermarks of the Rx FIFO for when the hardware should transmit PAUSE frames (XON and XOFF, respectively), need to be tuned for more efficient use of the FIFO. The logic to set the thresholds for parts that support early-receive (ERT) was also wrong in that it should check whether jumbo frames are in use.

2009-06-02mlx4_en: multiqueue supportYevgeny Petrilin
By default the driver opens 8 TX queues (defined by MLX4_EN_NUM_TX_RINGS). If the driver is configured to support Per Priority Flow Control, we open 8 additional TX rings. dev->real_num_tx_queues is always set to be MLX4_EN_NUM_TX_RINGS. The mlx4_en_select_queue() function uses standard hashing (skb_tx_hash) in case that PPFC is not supported or the skb contain a vlan tag, otherwise the queue is selected according to vlan priority.

2009-06-02e1000: add missing length check to e1000 receive routineNeil Horman
Patch to fix bad length checking in e1000. E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000. This is lifted straight from e1000e, and prevents small frames from causing the underflow described above Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Tested-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: David S.

2009-06-02forcedeth: add phy_power_down parameter, leave phy powered up by default (v2)Ed Swierk
Add a phy_power_down parameter to forcedeth: set to 1 to power down the phy and disable the link when an interface goes down; set to 0 to always leave the phy powered up. The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

2009-06-01can: sja1000: stop misusing member base_addr of struct net_deviceWolfgang Grandegger
As discussed on the netdev mailing list, the member "base_addr" of "struct net_device" should not be (mis)used to store the virtual address to the SJA1000 register area. According to David Miller, it's only use is to allow ISA and similar primitive bus devices to have their I/O ports changed via ifconfig. The virtual address is now stored in the private data structure of the SJA1000 device and the callback functions use "struct sja1000_priv" instead of the unneeded "struct net_device".

2009-05-29net: convert unicast addr listJiri Pirko
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.
