Since unregister_netdevice_notifier() will replay the NETDEV_DOWN and NETDEV_UNREGISTER_EVENTS, the cnic_dev_list will be cleaned up automatically. The loop to cleanup the cnic_dev_list can be removed in cnic_release(). Signed-off-by: NMichael Chan <mchan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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: NMichael Chan <mchan@broadcom.com> Signed-off-by: NDavid S.

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.

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.

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: NDavid S.

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.

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.

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.

Inspired by commit f09e2249 (macvtap: restore vlan header on user read). This patch adds hardware vlan tx support for tuntap.

The MinnowBoard uses an AR803x PHY with the PCH GBE which requires special handling. Use the MinnowBoard PCI Subsystem ID to detect this and add a pci_device_id.driver_data structure and functions to handle platform setup. The AR803x does not implement the RGMII 2ns TX clock delay in the trace routing nor via strapping. Add a detection method for the board and the PHY and enable the TX clock delay via the registers. This PHY will hibernate without link for 10 seconds. Ensure the PHY is awake for probe and then disable hibernation. A future improvement would be to convert pch_gbe to using PHYLIB and making sure we can wake the PHY at the necessary times rather than permanently disabling it.

Idea of this patch is to add optional limitation of number of unsent bytes in TCP sockets, to reduce usage of kernel memory. TCP receiver might announce a big window, and TCP sender autotuning might allow a large amount of bytes in write queue, but this has little performance impact if a large part of this buffering is wasted : Write queue needs to be large only to deal with large BDP, not necessarily to cope with scheduling delays (incoming ACKS make room for the application to queue more bytes) For most workloads, using a value of 128 KB or less is OK to give applications enough time to react to POLLOUT events in time (or being awaken in a blocking sendmsg()) This patch adds two ways to set the limit : 1) Per socket option TCP_NOTSENT_LOWAT 2) A sysctl (/proc/sys/net/ipv4/tcp_notsent_lowat) for sockets not using TCP_NOTSENT_LOWAT socket option (or setting a zero value) Default value being UINT_MAX (0xFFFFFFFF), meaning this has no effect. This changes poll()/select()/epoll() to report POLLOUT only if number of unsent bytes is below tp->nosent_lowat Note this might increase number of sendmsg()/sendfile() calls when using non blocking sockets, and increase number of context switches for blocking sockets. Note this is not related to SO_SNDLOWAT (as SO_SNDLOWAT is defined as : Specify the minimum number of bytes in the buffer until the socket layer will pass the data to the protocol) Tested: netperf sessions, and watching /proc/net/protocols "memory" column for TCP With 200 concurrent netperf -t TCP_STREAM sessions, amount of kernel memory used by TCP buffers shrinks by ~55 % (20567 pages instead of 45458) lpq83:~# echo -1 >/proc/sys/net/ipv4/tcp_notsent_lowat lpq83:~# (super_netperf 200 -t TCP_STREAM -H remote -l 90 &); sleep 60 ; grep TCP /proc/net/protocols TCPv6 1880 2 45458 no 208 yes ipv6 y y y y y y y y y y y y y n y y y y y TCP 1696 508 45458 no 208 yes kernel y y y y y y y y y y y y y n y y y y y lpq83:~# echo 131072 >/proc/sys/net/ipv4/tcp_notsent_lowat lpq83:~# (super_netperf 200 -t TCP_STREAM -H remote -l 90 &); sleep 60 ; grep TCP /proc/net/protocols TCPv6 1880 2 20567 no 208 yes ipv6 y y y y y y y y y y y y y n y y y y y TCP 1696 508 20567 no 208 yes kernel y y y y y y y y y y y y y n y y y y y Using 128KB has no bad effect on the throughput or cpu usage of a single flow, although there is an increase of context switches.
