2010-02-03sfc: Replace PHY MDIO test with an 'alive' testBen Hutchings
SFC9000-family boards do not all use MDIO PHYs, so we need a different test for PHY aliveness. Introduce a PHY operation test_alive(). For PHYs attached to Falcon, use a common implementation based on the existing PHY MDIO test. For PHYs managed through MCDI, use the appropriate MCDI request. Change test name in ethtool from 'core mdio' to 'phy alive'. Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

2010-02-03MCS7830 USB-Ether: resume _with_ working link, via .reset_resume supportAndreas Mohr
ChangeLog: Implement .reset_resume support to retain a live network connection during suspend despite USB power loss. - rework operation to reference cached data in mcs7830_data and netdev->dev_addr - update netdev->dev_addr only in case new MAC was set successfully . Tests done: . ethtool -d pre-/post-suspend: register values match . running ssh session suspend, resume: works . ifdown device, suspend, resume: works . ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1 after card replug works) . verified identical MAC in ifconfig post-resume (ok, should be verified on network side to be fully certain...)

2010-02-02virtio_net: Defer skb allocation in receive path Date: Wed, 13 Jan 2010 ↵Shirley Ma
12:53:38 -0800 virtio_net receives packets from its pre-allocated vring buffers, then it delivers these packets to upper layer protocols as skb buffs. So it's not necessary to pre-allocate skb for each mergable buffer, then frees extra skbs when buffers are merged into a large packet. This patch has deferred skb allocation in receiving packets for both big packets and mergeable buffers to reduce skb pre-allocations and skb frees. It frees unused buffers by calling detach_unused_buf in vring, so recv skb queue is not needed.

2010-02-02virtio: Add ability to detach unused buffers from vringsShirley Ma
There's currently no way for a virtio driver to ask for unused buffers, so it has to keep a list itself to reclaim them at shutdown. This is redundant, since virtio_ring stores that information.

2010-02-02can: deny filterlist access on non-CAN interfacesOliver Hartkopp
In commit 20dd3850bcf860561496827b711fa10fecf6e787 "can: Speed up CAN frame receiption by using ml_priv" the formerly used hlist of receiver lists for each CAN netdevice has been replaced. The hlist content ensured only CAN netdevices to be accessed by the can_rx_(un)register() functions which accidently dropped away together with the hlist receiver implementation.

2010-01-28sched: add head drop fifo queueHagen Paul Pfeifer
This adds an additional queuing strategy, called pfifo_head_drop, to remove the oldest skb in the case of an overflow within the queue - the head element - instead of the last skb (tail). To remove the oldest skb in congested situations is useful for sensor network environments where newer packets reflect the superior information.
