2011-07-07vmxnet3: round down # of queues to power of twoShreyas Bhatewara2-2/+6
vmxnet3 device supports only power-of-two number of queues. The driver therefore needs to check this and rounds down the number of queues to the nearest power of two.

2011-07-05vmxnet3: fix starving rx ring whenoc_skb kb failsShreyas Bhatewara2-43/+96
If the rx ring is completely empty, then the device may never fire an rx interrupt. Unfortunately, the rx interrupt is what triggers populating the rx ring with fresh buffers, so this will cause networking to lock up. This patch replenishes the skb in recv descriptor as soon as it is peeled off while processing rx completions. If the skb/buffer allocation fails, existing one is recycled and the packet in hand is dropped. This way none of the RX desc is ever left empty, thus avoiding starvation Signed-off-by: Scott J.

2011-06-16tun: teach the tun/tap driver to support netpollNeil Horman1-1/+23
Commit 8d8fc29d02a33e4bd5f4fa47823c1fd386346093 changed the behavior of slave devices in regards to netpoll. Specifically it created a mutually exclusive relationship between being a slave and a netpoll-capable device. This creates problems for KVM because guests relied on needing netconsole active on a slave device to a bridge. Ideally libvirtd could just attach netconsole to the bridge device instead, but thats currently infeasible, because while the bridge device supports netpoll, it requires that all slave interface also support it, but the tun/tap driver currently does not. The most direct solution is to teach tun/tap to support netpoll, which is implemented by the patch below. I've not tested this yet, but its pretty straightforward.

2011-06-16dp83640: drop PHY status frames in the driver.Richard Cochran1-2/+2
The dp83640 PHY provides time stamp and other information via special PHY status frames. Previously, the driver decoded the frames and then let the network stack drop them. This works fine when the PTP messages come over UDP. However, when receiving PTP messages via L2 packets, this creates a problem. The status frames use the official PTP destination MAC address, and so they are delivered to user space along with the "real" frames, causing confusion for applications. This commit fixes the issue by simply dropping the PHY status frames in the driver. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S.
