The driver uses dev_err when enabling of AER fails (e.g. PCIe AER is not supported). The dev_info is more appropriate to avoid console pollution. Cc: sathya.perla@emulex.com Cc: subbu.seetharaman@emulex.com Cc: ajit.khaparde@emulex.com Signed-off-by:

The PTP_CAPABLE tg3 devices have a gpio output that is toggled when the free running counter matches a watchdog value. This patch adds support to set the watchdog and enable this feature. Since the output is controlled via bits in the EAV_REF_CLCK_CTL register, we have to read-modify-write it when we stop/resume. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by:

Previously, when the interface was brought down, the driver would set the power state to D3hot. In D3hot, we don't have access to the NVRAM. This patch removes the call to set the power state to PCI_D3hot in close. A following patch will implement the shutdown handler to properly set the D3hot state when the system is going down. Doing the above means that the TG3_PHYFLG_IS_LOW_POWER should not be checked to validate access to the NVRAM. Signed-off-by:

During probe, the driver is incorrectly switching the power to Vaux on the 5717 and later devices. At this point, we are in D0 state and drawing maximum power. We also definitely have Vmain available. It doesn't make sense to switch to Vaux since it has a lesser maximum power draw and we might go over the limit. On a new system, we observe that not all ports are recognized in some of the slots with this call in place. Signed-off-by:

After this earlier commit to simplify probing: commit 4bd9b0ff cnic, bnx2x, bnx2: Simplify cnic probing. we can now reliably receive netdev events and we can simplify the handling of these events. We now remove the logic that tries to handle missed NETDEV_REGISTER events. This change will allow cleanup to be simplified in the next patch. We can now rely on the play back of netdev events during unregister_netdevice_notifier() to cleanup the structures. Signed-off-by:

This commit adds new firmware command and new firmware event. The firmware raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ command. At the moment the supported operation is adding/removing multicast entries which are used by the firmware for handling NCSI traffic in B0 steering mode. Also, had to swap the order of mlx4_init_mcg_table() and mlx4_init_eq_table() to make sure that driver will get events only after resources are initialized to handle it. Signed-off-by:

Fix a race between BlueFlame flow and stamping in post send flow. Example: SW: Build WQE 0 on the TX buffer, except the ownership bit SW: Set ownership for WQE 0 on the TX buffer SW: Ring doorbell for WQE 0 SW: Build WQE 1 on the TX buffer, except the ownership bit SW: Set ownership for WQE 1 on the TX buffer HW: Read WQE 0 and then WQE 1, before doorbell was rung/BF was done for WQE 1 HW: Produce CQEs for WQE 0 and WQE 1 SW: Process the CQEs, and stamp WQE 0 and WQE 1 accordingly (on the TX buffer) SW: Copy WQE 1 from the TX buffer to the BF register - ALREADY STAMPED! HW: CQE error with index 0xFFFF - the BF WQE's control segment is STAMPED, so the BF index is 0xFFFF. Error: Invalid Opcode. As a result QP enters the error state and no traffic can be sent. Solution: When stamping - do not stamp last completed wqe. Signed-off-by:

Jeff Kirsher says: ==================== This series contains updates to e100 and e1000e. The e100 patch from Andy simply updates the netif_printk() to use %*ph to dump small buffers. The changes to e1000e include a fix from Dean Nelson to resolve a issue where a pci_clear_master() was accidentally dropped during a conflict resolution. Wei Young provides 2 patches, one removes an assignment of the default ring size because it was a duplicate. The second changes the packet split receive structure to use PS_PAGE_BUFFERS macro for the length so that problems won't occur when the length is changed. The remaining patches for e1000e are from Bruce Allan, where he provides a number of fixes and updates for I218. In addition, a fix for 82583 which can disappear off the PCIe bus, to resolve this, disable ASPM L1. Bruce also provides a fix to a previous commit (commit e60b22c5 e1000e: fix accessing to suspended device) so that devices are only taken out of runtime power management for those ethtool operations that must access device registers. ==================== Signed-off-by:

A previous patch (commit e60b22c5 e1000e: fix accessing to suspended device) added .begin and .complete ethtool driver callbacks so that the device was resumed from Runtime Power Management (RPM) suspend state for all ethtool operations. This is overkill for operations which do not need to access any registers in the device. This patch makes it so that the device is taken out of RPM suspend only for those ethtool operations that must access device registers. Signed-off-by:

Tx hang is an unintended consequence of another workaround that is in the EEPROM for an issue with the firmware at 10Mbps when K1 (a power mode of the MAC-PHY interconnect) is enabled. The issue is resolved by setting appropriate Tx re-transmission timeouts in the PHY and associated K1 entry times in the MAC to allow enough transmissions to occur without triggering a Tx hang. A similar change is needed when linked at 10Mbps to improve latency. Signed-off-by:

The jumbo frame configuration in the MAC/PHY should be reverted on 82579 and newer parts when the interface is brought down (not just when the MTU is changed back to standard frame size) otherwise iAMT connections (e.g. SoL, IDE-R) will be dropped and cannot be re-acquired until the MTU is changed again.

In attempting to resolve a minor merge conflict, commit e5f2ef7a (Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net) accidentally dropped a call to pci_clear_master() that was intended to remain in place. Commit 4e0855df (e1000e: fix pci-device enable-counter balance) replaced a call to pci_disable_device() by one to pci_clear_master(). And then commit 66148bab (e1000e: fix runtime power management transitions) deleted a number of lines starting two lines following that call. This patch restores the call to pci_clear_master() in __e1000_shutdown(). v2: added summary lines (enclosed in parens) following commit IDs Signed-off-by:

This patch centralizes computing of max rx/tx qlen, because: - RX_QLEN()/TX_QLEN() is called in hot path - computing depends on device's usb speed, now we have ls/fs, hs, ss, so more checks need to be involved - in fact, max rx/tx qlen should not only depend on device USB speed, but also depend on ethernet link speed, so we need to consider that in future. - if SG support is done, max tx qlen may need change too Generally, hard_mtu and rx_urb_size are changed in bind(), reset() and link_reset() callback, and change mtu network operation, this patches introduces the API of usbnet_update_max_qlen(), and calls it in above path.
