* wimax/i2400m: generate fake source MAC address with random_ether_addr()Inaky Perez-Gonzalez2009-05-283-1/+10
| | | | | | | | | | | | | | | | The WiMAX i2400m driver needs to generate a fake source MAC address to fake an ethernet header (for destination, the card's MAC is used). This is the source of the packet, which is the basestation it came from. The basestation's mac address is not usable for this, as it uses its own namespace and it is not always available. Currently the fake source MAC address was being set to all zeros, which was causing trouble with bridging. Use random_ether_addr() to generate a proper one that creates no trouble.

* ixgbe: only register DCA requester onceAlexander Duyck2009-05-211-20/+4
| | | | | | | | | | The current driver tries to re-register the DCA requester after reset and this is not correct. This change makes it so all we are doing is resetting the DCA registers after reset and not re-adding the requester.

* igb: do not re-register DCA requester on device resetAlexander Duyck2009-05-211-3/+9
| | | | | | | | | | The current driver is re-registering the DCA requester after every reset. Instead of doing this we should only be updating the on board DCA registers and not unregistering/re-registering our requester.

* ixgbe: Change Direct Attach Twinax cable detection for SFP+ NICsPeter P Waskiewicz Jr2009-05-192-13/+11
| | | | | | | | | | | | | The SFF specification for Direct Attach cable detection has now been ratified. Previously, DA cable detect was looking at the Twinaxial bit in byte 9 of the SFP+ EEPROM. The spec now defines active and passive DA cables in byte 8 of the SFP+ EEPROM. This patch changes the cable detection for both 82598 and 82599 SFP+ adapters to conform to the new spec.

* r8169: allow true forced mode settingfrançois romieu2009-05-191-53/+59
| | | | | | | | | | | | | | | | | | Due to mostly historic reasons, including a lack of reliability of the link handling (especially with the older 8169), the current r8169 driver emulates forced mode setting by limiting the advertised modes. With this change the driver allows real 10/100 forced mode settings on the 8169 and 8101/8102. Original idea by Vincent Steenhoute. The RTL_GIGA_MAC_VER_03 tweak was extracted from Realtek's r8169 v6.010.00 driver.

* net: release dst entry in dev_hard_start_xmit()Eric Dumazet2009-05-187-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One point of contention in high network loads is the dst_release() performed when a transmited skb is freed. This is because NIC tx completion calls dev_kree_skb() long after original call to dev_queue_xmit(skb). CPU cache is cold and the atomic op in dst_release() stalls. On SMP, this is quite visible if one CPU is 100% handling softirqs for a network device, since dst_clone() is done by other cpus, involving cache line ping pongs. It seems right place to release dst is in dev_hard_start_xmit(), for most devices but ones that are virtual, and some exceptions. David Miller suggested to define a new device flag, set in alloc_netdev_mq() (so that most devices set it at init time), and carefuly unset in devices which dont want a NULL skb->dst in their ndo_start_xmit(). List of devices that must clear this flag is : - loopback device, because it calls netif_rx() and quoting Patrick : "ip_route_input() doesn't accept loopback addresses, so loopback packets already need to have a dst_entry attached." - appletalk/ipddp.c : needs skb->dst in its xmit function - And all devices that call again dev_queue_xmit() from their xmit function (as some classifiers need skb->dst) : bonding, vlan, macvlan, eql, ifb, hdlc_fr Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

| | | | | | | | | | | | Sysfs files for a network device can not unconditionally take the rtnl_lock as the bonding sysfs files do. If someone accesses those sysfs files while the network device is being unregistered with the rtnl_lock held we will deadlock. So use trylock and restart_syscall to avoid this problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | After 2.6.29, PPC no more admits passing NULL to the dev parameter of the DMA API. The result is a BUG followed by solid lock-up when the mv643xx_eth driver brings an interface up. The following patch makes the driver work on my Pegasos again; it is mostly a search and replace of NULL by mp->dev->dev.parent in dma allocation/freeing/mapping/unmapping functions.

| * bonding: fix link down handling in 802.3ad modeStephen Hemminger2009-05-171-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the purposes of bonding is to allow for redundant links, and failover correctly if the cable is pulled. If all the members of a bonded device have no carrier present, the bonded device itself needs to report no carrier present to user space so management tools (like routing daemons) can respond. Bonding in 802.3ad mode does not work correctly for this because it incorrectly chooses a link that is down as a possible aggregator.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the i2400m receives data and the device indicates there has to be reordering, we keep an sliding window implementation to sort the packets before sending them to the network stack. One of the "operations" that the device indicates is "queue a packet and update the window start". When the queue is empty, this is equivalent to "deliver the packet and update the window start". That case was optimized in i2400m_roq_queue_update_ws() so that we would not pointlessly queue and dequeue a packet. However, when the optimization was active, it wasn't updating the window start. That caused the reorder management code to get confused later on with what seemed to be wrong reorder requests from the device. Thus the fix implemented is to do the right thing and update the window start in both cases, when the queue is empty (and the optimization is done) and when not.
