dcbml_setnumtcs wasn't checking for the presence of the setnumtcs function. Instead, it was checking for setstate which was a bug. Signed-off-by:

This issue was initially reported by Joerg Roedel <joerg.roedel@amd.com> It appears that ixgbe has had a long standing bug where it was unmapping a different size than it had mapped. ixgbe 0000:02:00.0: PCI-DMA: device driver frees DMA memory with different sizes than it mapped. ixgbe 0000:02:00.0: PCI-DMA: device driver frees DMA memory with different size [device address=0x0000000003fed812] [map size=258 bytes] [unmap size=256 bytes] Pid: 6178, comm: rmmod Not tainted 2.6.28-rc5 #4 Call Trace: [<ffffffff8022a2ae>] iommu_queue_inv_iommu_pages+0x5e/0x70 [<ffffffff80225956>] check_unmap+0x1c6/0x240 [<ffffffff80225ff5>] debug_unmap_single+0xb5/0x110 [<ffffffffa0213997>] ixgbe_clean_rx_ring+0x147/0x220 [<ffffffffa0214d7d>] ixgbe_down+0x2fd/0x3d0 [ixgbe] [<ffffffffa02150b3>] ixgbe_close+0x13/0xc0 [ixgbe] [<ffffffff80431326>] dev_close+0x56/0xa0 [<ffffffff804313b3>] rollback_registered+0x43/0x220 [<ffffffff804315a5>] unregister_netdevice+0x15/0x60 [<ffffffff80431601>] unregister_netdev+0x11/0x20 [<ffffffffa021aef8>] ixgbe_remove+0x48/0x16e [ixgbe] [<ffffffff80386ffc>] pci_device_remove+0x2c/0x60 [<ffffffff803ef929>] __device_release_driver+0x99/0x100 [<ffffffff803efa48>] driver_detach+0xb8/0xc0 [<ffffffff803eea6e>] bus_remove_driver+0x8e/0xd0 [<ffffffff80387374>] pci_unregister_driver+0x34/0x90 [<ffffffff8026c6c7>] sys_delete_module+0x1c7/0x2a0 [<ffffffff802a9ce9>] do_munmap+0x349/0x390 [<ffffffff80374481>] __up_write+0x21/0x150 [<ffffffff8020c30b>] system_call_fastpath+0x16/0x1b Signed-off-by:

This patch adds support for SMSC's LAN9420 PCI ethernet controller to ethtool's dump registers (-d) command. This patch is for use with an accompanying ethtool patch, which decodes the register dump. Signed-off-by:

Currently efx_mtd_rename() can race with the probe() and remove() functions. Move probe() before device registration and remove() after unregistration. Move initialisation/update of all names based on the netdev name into a new function and call it under the RTNL immediately after registration. Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> efx_pci_probe_main() can return success despite a reset being scheduled. Catch this and retry or abort probe depending on the reset type. Signed-off-by:

Some of the PHY type names are overly generic. Change them to include the model numbers of the PHYs they represent. Correct the model number reference at the top of xfp_phy.c. Signed-off-by:

ethtool must contend with the MTD driver for the SPI bus lock, which may carry out long operations such as flash erase. Allow it to be interrupted while waiting. Signed-off-by:

Our ethtool self-test result names each begin with a component name. For some results this is "port0", which is not very meaningful. Change that to "rx" or "phy" as appropriate. Signed-off-by:

Add type codes for the new PHY and rename the SFX7101 type code. Add definition of clause 22 extension MMD. Adapt the 10Xpress SFX7101 code to support the SFT9001 as well. Clean up register definitions. Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> MAC, PHY and board events may be separately enabled and signalled. Our current arrangement of chaining the polling functions can result in events being missed. Change them to be more independent. Signed-off-by:

Add infrastructure for auto-negotiation of speed, duplex and flow control. When using 10Xpress, auto-negotiate flow control. While we're at it, clean up the code to warn when partner is not 10GBASE-T capable. Signed-off-by:

The SFC4000 has a separate MAC for use at sub-10G speeds. Introduce an efx_mac_operations structure with implementations for the two MACs. Switch between the MACs as necessary. PHY settings are independent of the MAC, so add get_settings() and set_settings() to efx_phy_operations. Also add macs field to indicate which MACs the PHY is connected to. Signed-off-by:

We often want to set or clear a flag in an MDIO register, but avoid writing if no change is required since this can have side-effects. Encapsulate this in a function, mdio_clause45_set_flag(). Signed-off-by:

In a bidirectional forwarding test, we find that the best performance is achieved by sending the TX completion interrupts from one NIC to a CPU which shares an L2 cache with RX completion interrupts from the other NIC. To facilitate this, add an option (through a module parameter) to create separate channels for RX and TX completion with separate IRQs when MSI-X is available. Signed-off-by:
