2012-04-17dmfe: enforce consistent timing delay.françois romieu
The driver does not always use the same timing for what looks like the same operations. - DCR0 Use the same udelay everywhere for reset. Upper bound is 100 us. - DCR9 Use 5us delay for srom clock. 1us delay for phy_write_1bit (writes PHY_DATA_[01]) are not changed as they stay withing a 2,5MHz MDIO clock range.

2012-04-15macvlan: add FDB bridge ops and macvlan flagsJohn Fastabend
This adds FDB bridge ops to the macvlan device passthru mode. Additionally a flags field was added and a NOPROMISC bit to allow users to use passthru mode without the driver calling dev_set_promiscuity(). The flags field is a u16 placed in a 4 byte hole (consuming 2 bytes) of the macvlan_dev struct. We want to do this so that the macvlan driver or stack above the macvlan driver does not have to process every packet. For the use case where we know all the MAC addresses of the endstations above us this works well. This patch is a result of Roopa Prabhu's work. Follow up patches are needed for VEPA and VEB macvlan modes. v2: Change from distinct nopromisc mode to a flags field to configure this. This avoids the tendency to add a new mode every time we need some slightly different behavior. v3: fix error in dev_set_promiscuity and add change and get link attributes for flags.

2012-04-15ixgbe: UTA table incorrectly programmedGreg Rose
The UTA table was being set to the functional equivalent of promiscuous mode. This was resulting in traffic from the virtual function being flooded onto the wire and the PF device. This resulted in additional overhead for VF traffic sent to the network and in the case of traffic sent to the PF or another VF resulted in unwanted packets on the wire. This was actually not the intended behavior. Now that we can program the embedded switch correctly we can remove this snippit of code. Users who want to support this should configure the FDB correctly using the FDB ops.

2012-04-15atl1: do not drop rx/tx interrupts before they are scheduledTony Zelenoff
To prevent interrupts lost they should be dropped only if they are scheduled via napi interfaces. In other case, there is exists situation when napi handler process TX interrupt, stay in RX processing and in that moment any other interrupt received. Then before this patch TX bit in ISR will be cleaned, napi schedule will not occur in case of currently processing event and TX interrupt definitely will be lost.

2012-04-15virtio-net: send gratuitous packets when neededJason Wang
As hypervior does not have the knowledge of guest network configuration, it's better to ask guest to send gratuitous packets when needed. This patch implements VIRTIO_NET_F_GUEST_ANNOUNCE feature: hypervisor would notice the guest when it thinks it's time for guest to announce the link presnece. Guest tests VIRTIO_NET_S_ANNOUNCE bit during config change interrupt and woule send gratuitous packets through netif_notify_peers() and ack the notification through ctrl vq. We need to make sure the atomicy of read and ack in guest otherwise we may ack more times than being notified. This is done through handling the whole config change interrupt in an non-reentrant workqueue. Signed-off-by: Jason Wang <jasowang@redhat.com> Acked-by: Michael S.

2012-04-14net/ethernet: ks8851_mll fix rx frame buffer overflowDavide Ciminaghi
At the beginning of ks_rcv(), a for loop retrieves the header information relevant to all the frames stored in the mac's internal buffers. The number of pending frames is stored as an 8 bits field in KS_RXFCTR. If interrupts are disabled long enough to allow for more than 32 frames to accumulate in the MAC's internal buffers, a buffer overflow occurs. This patch fixes the problem by making the driver's frame_head_info buffer big enough. Well actually, since the chip appears to have 12K of internal rx buffers and the shortest ethernet frame should be 64 bytes long, maybe the limit could be set to 12*1024/64 = 192 frames, but 255 should be safer.

2012-04-14e1000e: issues in Sx on 82577/8/9Bruce Allan
A workaround was previously put in the driver to reset the device when transitioning to Sx in order to activate the changed settings of the PHY OEM bits (Low Power Link Up, or LPLU, and GbE disable configuration) for 82577/8/9 devices. After further review, it was found such a reset can cause the 82579 to confuse which version of 82579 it actually is and broke LPLU on all 82577/8/9 devices. The workaround during an S0->Sx transition on 82579 (instead of resetting the PHY) is to restart auto-negotiation after the OEM bits are configured; the restart of auto-negotiation activates the new OEM bits as does the reset. With 82577/8, the reset is changed to a generic reset which fixes the LPLU bits getting set wrong.
