2010-02-03ixgbe: Fix return of invalid txqKrishna Kumar
a developer had complained of getting lots of warnings: "eth16 selects TX queue 98, but real number of TX queues is 64" http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg02200.html As there was no follow up on that bug, I am submitting this patch assuming that the other return points will not return invalid txq's, and also that this fixes the bug (not tested).

2010-02-03ixgbe: Fix ixgbe_tx_map error pathAnton Blanchard
Commit e5a43549f7a58509a91b299a51337d386697b92c (ixgbe: remove skb_dma_map/unmap calls from driver) looks to have introduced a bug in ixgbe_tx_map. If we get an error from a PCI DMA call, we loop backwards through count until it becomes -1 and return that. The caller of ixgbe_tx_map expects 0 on error, so return that instead.

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.

2010-02-02virtio_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.

2010-01-28cdc_ether: Partially revert "usbnet: Set link down initially ..."Ben Hutchings
Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down initially for drivers that update link state") changed the initial link state in cdc_ether and other drivers based on the understanding that the devices they support generate link change interrupts. However, this is optional in the CDC Ethernet protocol, and two users have reported in <http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state for their devices remains down. Therefore, revert the change in cdc_ether. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Tested-by: Avi Rozen <avi.rozen@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
