* PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine2014-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
* jme: Fix unmap loop counting error:Neil Horman2014-05-14
| | | | | | | | | | | | | | In my recent fix (76a691d0a: fix dma unmap warning), Ben Hutchings noted that my loop count was incorrect. Where j started at startidx, it should have started at zero, and gone on for count entries, not to endidx. Additionally, a DMA resource exhaustion should drop the frame and (for now), return NETDEV_TX_OK, not NETEV_TX_BUSY. This patch fixes both of those issues: Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: Ben Hutchings <ben@decadent.org.uk> CC: "David S.

* jme: Fix DMA unmap warningNeil Horman2014-05-07
| | | | | | | | | | | | The jme driver forgot to check the return status from pci_map_page in its tx path, causing a dma api warning on unmap. Easy fix, just do the check and augment the tx path to tell the stack that the driver is busy so we re-queue the frame.

* net: vlan: add protocol argument to packet tagging functionsPatrick McHardy2013-04-19
| | | | | | | | | | Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* drivers/net: fix tasklet misuse issueXiaotian Feng2012-11-14
| | | | | | | | | | | | | | | | | In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable in the driver init code, then tasklet_enable when it is opened. This makes tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally, drivers should use tasklet_init/tasklet_kill on device open/remove, and use tasklet_disable/tasklet_enable on device suspend/resume.
