* e1000: fix flow control thresholdsJesse Brandeburg2009-07-06
| | | | | | | | | | | | | | | | | | | when testing the jumbo frames with pages patch, the stats would show rx_missed errors (dropped packets) even when connected to a link partner with flow control enabled. this indicates that for this MTU (9000) the flow control thresholds are not adjusting correctly. In fact, before this change, the FCRTH (xoff threshold) is 36864 when the fifo size is only 40000, with 9000 byte MTU. fix it so that we at least have room for one frame after we send the xoff.

* e1000: implement jumbo receive with partial descriptorsJesse Brandeburg2009-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is code extremely similar to what is committed in e1000e already. e1000 will no longer request 32kB slab buffers to support jumbo frames on PCI/PCI-X adapters. This will significantly reduce the likelyhood of order:3 allocation failures. This new code adds support for using pages as receive buffers, and the driver will chain multiple pages together to build a jumbo frame for OS consumption. The hardware takes a power of two buffer size and will dump as much data as it can receive into 1 or more buffers. The benefits of applying this are 1) stop akpm's dissing :-) of this lame e1000 behavior [1] 2) more efficient memory allocation (half) when using jumbo frames, which will also allow for much better socket utilization with jumbos since the socket is charged for the full allocation of each receive buffer, regardless of how much is used. 3) this was a feature request by a customer 4) copybreak for small packets < 256 bytes still applies [1] http://lkml.org/lkml/2008/7/10/68 http://article.gmane.org/gmane.linux.network/130986 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> CC: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

* e1000: allow ethtool coalesece to adjust interrupts per secondJesse Brandeburg2009-07-06
| | | | | | | | | | | | | | | | | | | | | | This patch allows on-the-fly adjustment of the interrupts per second generated by e1000 devices 82545/82546 (hardware support of ITR register is a requirement) adjust using this command: ethtool -C eth0 rx-usecs 10 where 10 is 10 microseconds per interrupt interval, so 10 = 100,000 interrupts per second, and 125 = 8000 interrupts per second. changes should be immediate. 1,3 are special values and indicate the automatic tuning mode to the driver, where 1 is 4000-90000 interrupts per second and 3 is 4000-20000 interrupts per second and is the driver default.

* e1000: return PCI_ERS_RESULT_DISCONNECT on permanent errorAndre Detsch2009-06-30
| | | | | | | | | | | | | | | | PCI drivers that implement the io_error_detected callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is pci_channel_io_perm_failure.

* net: group address list and its countJiri Pirko2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions). I wanted to introduce this patch before I'll post a multicast lists conversion.

* net: skb_shared_info optimizationEric Dumazet2009-06-08
| | | | | | | | | | | | | | | | skb_dma_unmap() is quite expensive for small packets, because we use two different cache lines from skb_shared_info. One to access nr_frags, one to access dma_maps[0] Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements, let dma_head alone in a new dma_head field, close to nr_frags, to reduce cache lines misses.

| * e1000: add missing length check to e1000 receive routineNeil Horman2009-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a recent fix to e1000 (commit 15b2bee2) caused KVM/QEMU/VMware based virtualized e1000 interfaces to begin failing when resetting. This is because the driver in a virtual environment doesn't get to run instructions *AT ALL* when an interrupt is asserted. The interrupt code runs immediately and this recent bug fix allows an interrupt to be possible when the interrupt handler will reject it (due to the new code), when being called from any path in the driver that holds the E1000_RESETTING flag. the driver should use the __E1000_DOWN flag instead of the __E1000_RESETTING flag to prevent interrupt execution while reconfiguring the hardware.

| * e1000: fix bug with shared interrupt during resetJesse Brandeburg2009-01-27
| | | | | | | | | | | | | | | | | | | | | | | | A nasty bug was found where an MTU change (or anything else that caused a reset) could race with the interrupt code. The interrupt code was entered by a shared interrupt during the MTU change. This change prevents the interrupt code from running while the driver is in the middle of its reset path.

* net: Remove unused netdev arg from some NAPI interfaces.Neil Horman2008-12-22
| | | | | | | | | | When the napi api was changed to separate its 1:1 binding to the net_device struct, the netif_rx_[prep|schedule|complete] api failed to remove the now vestigual net_device structure parameter. This patch cleans up that api by properly removing it.. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* netdev: add more functions to netdevice opsStephen Hemminger2008-11-20
| | | | | | | | | | | | This patch moves neigh_setup and hard_start_xmit into the network device ops structure. For bisection, fix all the previously converted drivers as well. Bonding driver took the biggest hit on this. Added a prefetch of the hard_start_xmit in the fast path to try and reduce any impact this would have.

| | | | | | | | | | | | | | | | | | | | | | | | Since dev->power.should_wakeup bit is used by the PCI core to decide whether the device should wake up the system from sleep states, set/unset this bit whenever WOL is enabled/disabled using e1000_set_wol(). Accordingly, use device_can_wakeup() for checking if wake-up is supported by the device. Signed-off-by: "Rafael J.

* | netdevice: safe convert to netdev_priv() #part-2Wang Chen2008-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

* | drivers/net: Kill now superfluous ->last_rx stores.David S. Miller2008-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>

* e1000: don't generate bad checksums for tcp packets with 0 csumDave Graham2008-10-09
| | | | | | | | | | | | | | | | When offloading transmit checksums only, the driver was not correctly configuring the hardware to handle the case of a zero checksum. For UDP the correct behavior is to leave it alone, but for tcp the checksum must be changed from 0x0000 to 0xFFFF. The hardware takes care of this case but only if it is told the packet is tcp. same patch as e1000e Signed-off-by: Dave Graham <david.graham@intel.com> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
