Before PF asserting function reset, it should make sure that all its VFs have been ready, otherwise, it will cause some hardware errors. So this patch adds function hclge_func_reset_sync_vf() to synchronize VF before asserting PF function reset. For new firmware which supports command HCLGE_OPC_QUERY_VF_RST_RDY, we will try to query VFs' ready status within 30 seconds. And keep the old implementation for compatible with firmware which does not support this command. Signed-off-by:

Hardware supports up to 8 TX BD for non-TSO skb and 63 TX BD for TSO skb. Currently hns3 driver does not check the max BD num that required by a skb before filling desc, which may cause the hardware to issue a RAS error throug PCIe AER. This patch adds the max BD num check before filling desc, if the bd num is not within the hardware limit, it will record the error by ring->stats.sw_err_cnt counter and free the skb. This patch also cleans up the hns3_nic_bd_num function by changing the return type and removing an unnecessary check. Signed-off-by:

This patch adds tx_vlan_err, tx_l4_proto_err, tx_l2l3l4_err and tx_tso_err counter to tx process, in order to better debug the desc filling error. This patch also adds a missing u64_stats_update_* around ring->stats.sw_err_cnt and adds hns3_rl_err to limit the error printing in the IO patch. Signed-off-by:

Now we can use ethtool -d command to dump some registers. However, these registers information is not enough to find out where the problem is. This patch adds DFX registers information after original registers when use ethtool -d commmand to dump registers. Also, using macro replaces some related magic number. Signed-off-by:

Currently, the pause options of HNS3 shown like this: "RX/TX" is always the same with "RX negotiated/TX negotiated". Because of the driver covered the value of "RX/TX" with the value of "RX negotiated/TX negotiated" after adjust link. This patch records the pause configurations of the user, and never covered them in adjust link. Signed-off-by:

Currently, VF driver has two kinds of interrupts, reset & CMDQ RX. For revision 0x21, according to the UM, each interrupt should be cleared by write 0 to the corresponding bit, but the implementation writes 0 to the whole register in fact, it will clear other interrupt at the same time, then the VF will loss the interrupt. But for revision 0x20, this interrupt clear register is a read & write register, for compatible, we just keep the old implementation for 0x20. This patch fixes it, also, adds a new register for reading the interrupt status according to hardware user manual.

The current implementation of TCP MTU probing can considerably underestimate the MTU on lossy connections allowing the MSS to get down to 48. We have found that in almost all of these cases on our networks these paths can handle much larger MTUs meaning the connections are being artificially limited. Even though TCP MTU probing can raise the MSS back up we have seen this not to be the case causing connections to be "stuck" with an MSS of 48 when heavy loss is present. Prior to pushing out this change we could not keep TCP MTU probing enabled b/c of the above reasons. Now with a reasonble floor set we've had it enabled for the past 6 months. The new sysctl will still default to TCP_MIN_SND_MSS (48), but gives administrators the ability to control the floor of MSS probing. Signed-off-by:

Starting from commit d41a69f1 ("tcp: make tcp_sendmsg() aware of socket backlog") loopback flows got hurt, because for each skb sent, the socket receives an immediate ACK and sk_flush_backlog() causes extra work. Intent was to not let the backlog grow too much, but we went a bit too far. We can check the backlog every 16 skbs (about 1MB chunks) to increase TCP over loopback performance by about 15 % Note that the call to sk_flush_backlog() handles a single ACK, thanks to coalescing done on backlog, but cleans the 16 skbs found in rtx rb-tree.

Since node internal messages are passed directly to the socket, it is not possible to observe those messages via tcpdump or wireshark. We now remedy this by making it possible to clone such messages and send the clones to the loopback interface. The clones are dropped at reception and have no functional role except making the traffic visible. The feature is enabled if network taps are active for the loopback device. pcap filtering restrictions require the messages to be presented to the receiving side of the loopback device. v3 - Function dev_nit_active used to check for network taps. - Procedure netif_rx_ni used to send cloned messages to loopback device.
