If the hardware address of a underlying netdevice is changed, it is not enough to simply reset the bearer/links over this device. We also need to reflect this change in the TIPC bearer and node discovery structures aswell. This patch adds the necessary reinitialization of the node disovery mechanism following a hardware address change so that the correct originating media address is advertised in the discovery messages.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000e, igb, i40e and i40evf Anjali provides i40e fix to remove the ATR filter on RST as well as FIN packets. Cleans up add_del_fdir() because it was used and implemented only for the add, so change the name and drop a parameter. Adds the ability to drop a flow if we wanted to and adds a flow director message level to be used for flow director specific messages. Mitch fixes an issue on i40evf where the Tx watchdog handler was causing an oops when sending an admin queue message to request a reset because the admin queue functions use spinlocks. Greg provides a change to i40e to make the alloc and free queue vector calls orthogonal. Shannon fixes i40e to verify the eeprom checksum and firmware CRC status bits, and shutdown the driver if they fail. This change stops the processing of traffic, but does not kill the PF netdev so that the NVMUpdate process still has a chance at fixing the image. Also provides a fix to make sure the VSI has a netdev before trying to use it in the debugfs netdev_ops commands. Jakub Kicinski provides patches for e1000e and igb to fix a number issues found in the PTP code. v2: - drop patch 11 "i40e: Add a fallback debug flow for the driver" from the series based on feedback from David Miller ==================== Signed-off-by: -

Sathya Perla says: ==================== be2net: add vxlan offload support The first patch adds the FW cmds needed to configure the Skyhawk-R chip for supporting VxLAN offloads. The second patch implements the ndo_add/del_vxlan_port() methods and the plumbing for supporting RX/TX csum, TSO and RSS steering offloads for VxLAN traffic. v2 changes: NETIF_F_SG need not be set for hw_enc_features by the driver as it is done by the stack. v3 changes: * Defer FW cmds needed for VxLAN offloads to a workqueue * Reset FW to VxLAN offloads disabled state in the unload path v4 changes: * Revert the usage of workqueue (introduced in v3) to implement ndo_add/del_vxlan_port() as it is currently not needed (none of the FW cmd calls sleep.)

This patch mainly implements the add/del_vxlan_port() methods by invoking the needed FW cmds for supporting VxLAN offloads for Skyhawk-R. Signed-off-by:

Sathya Perla authored
This patch adds support for the FW cmds needed for VxLAN offloads on Skyhawk-R: 1) The VxLAN UDP port needs to be configured via the port-desc of SET_PROFILE_CONFIG_v1 cmd. This patch re-factors the be_set_profile_config() code (used so far only for setting VF QoS) to be used to set any type of descriptor. 2) The MANAGE_IFACE_FILTERS cmds is needed to convert a normal interface into a tunnel interface. This allows for RSS to work even on the inner TCP/UDP headers of VxLAN traffic. Signed-off-by:

igb has a single set of TX time stamping resources per NIC. Use a simple bit lock to avoid race conditions and leaking skbs when multiple TX rings try to claim time stamping. Signed-off-by:

skb_tx_timestamp() does not report software time stamp if SKBTX_IN_PROGRESS is set. According to timestamping.txt software time stamps are a fallback and should not be generated if hardware time stamp is provided. Move call to skb_tx_timestamp() after setting SKBTX_IN_PROGRESS. Signed-off-by:

Hardware may fail to report time stamp e.g.: - when hardware time stamping is not enabled - when time stamp is requested shortly after ifup Timeout time stamp reading work to prevent it from scheduling itself indefinitely. Report timeout events via system log and device stats. Signed-off-by:

The driver needs to verify the eeprom checksum and firmware crc status bits, and shutdown the driver if they fail. This code stops the processing of traffic, but doesn't kill the PF netdev so that the NVMUpdate process should still have a chance at fixing the image. The eeprom is checked on driver load and after an EMP reset, the latter of which should be generated after an NVMUpdate. Change-ID: I34deef21d2e16bf5a43c603cf8af27e6a29dc9d2 Signed-off-by:

The Tx watchdog handler runs in interrupt context, so it would cause an oops when sending an admin queue message to request a reset, because the admin queue functions use spinlocks. Instead, set a flag and let the reset task handle sending the request. Change-ID: I65879470b72963d9c308edfb8f45ac4fbba2c14f Signed-off-by:

Florian Fainelli says: ==================== net: remove empty MDIO bus reset functions This patchset removes all empty MDIO bus reset functions that we have in the tree (hopefully all of them). This function is optional for the MDIO bus code in drivers/net/phy/mdio_bus.c::mdiobus_register, the documentation is updated to reflect that. Having less call sites to update will allow us to implement a generic BMCR_RESET based PHY reset for MDIO buses that require to reset their PHYs before their PHY detection succeeds (e.g: HiSilicon hip04 current submission) and provide it as a helper. ==================== Signed-off-by: -

When the UniMAC block is configured to forward the CRC as part of the Ethernet frame (priv->crc_fwd_en, set by default), enabling the hardware RX checksum block unveiled that the dma_rxchk_bit was never set in the per-packet status bits (dma_flag in bcmgenet_desc_rx). This would make the chksum_ok variable to be never set to 1, and the networking stack would have to compute the packet checksums, which takes a substantial amount of time. In order for the RXCHK block to properly compute the packet checksum in hardware, we also need to set the RBUF_SKIP_FCS bit accordingly. Signed-off-by:
