Our VF has not implemented the ops for get_port_type. So when we executing ethtool ethx cmd of VF, hns3_get_link_ksettings will return directly. And we can not query anything. To support get_link_ksettings for VF, this patch replaces get_port_type with get_media_type. If the media type is HNAE3_MEDIA_TYPE_NONE, hns3_get_link_ksettings will return link information of VF. Fixes: 12f46bc1 ("net: hns3: Refine hns3_get_link_ksettings()") Signed-off-by:

When nic down, it firstly calls netif_tx_stop_all_queues(), then calls napi_disable(). But napi_disable() will wait current napi_poll finish, it may call netif_tx_wake_queue().

There are two tqp_num variables "hdev->tqp_num" and "kinfo->tqp_num" used in VF. "hdev->tqp_num" is the total tqp number allocated to the VF, and "kinfo->tqp_num" indicates the tqp number being used by the VF. Usually the two variables are equal. But for the case hdev->tqp_num larger than rss_size_max, and num_tc is 1, "kinfo->tqp_num" will be less than "hdev->tqp_num". In original codes, "hdev->tqp_num" is always used to traverse the tqp array of kinfo. It may cause null pointer error when "hdev->tqp_num" is larger than "kinfo->tqp_num" Fixes: e2cb1dec ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support") Signed-off-by:

There is a defect in hclge_ets_validate(). If each member of tc_tsa is not IEEE_8021QAZ_TSA_ETS, the variable total_ets_bw won't be updated. In this case, the check for value of total_ets_bw will fail. This patch fixes it by checking total_ets_bw only after it has been updated.

The previous commit to ravb had the side effect of making the PHY advertise Pause and Asym Pause, which previously did not happen. By default, phydev->supported has both forms of pause enabled, but phydev->advertising does not. The new phy_remove_link_mode() copies phydev->supported to phydev->advertising after removing the requested link mode. These Pause configuration bits appears it stops the PHY from completing Auto-Neg and the link remains down. Be explicit and remove the Pause and Asym Pause modes, so restoring the old behavior.

Håkon Bugge says: ==================== net: if_arp: use define instead of hard-coded value Struct arpreq contains the name of the device. All other places in the kernel, the define IFNAMSIZ is used to designate its size. But in if_arp.h, a literal constant is used. As it could be good reasons to use constants instead of the defines in include files under uapi, it seems to be OK to use the define here, without opening a can of worms in user-land. This because if_arp.h includes netdevice.h, which also uses IFNAMSIZ. For the distros I have checked, this also holds true for the use-land side. The series also fixes some incorrect indents. ==================== Signed-off-by: -

In current implementation, tls records are encrypted & transmitted serially. Till the time the previously submitted user data is encrypted, the implementation waits and on finish starts transmitting the record. This approach of encrypt-one record at a time is inefficient when asynchronous crypto accelerators are used. For each record, there are overheads of interrupts, driver softIRQ scheduling etc. Also the crypto accelerator sits idle most of time while an encrypted record's pages are handed over to tcp stack for transmission. This patch enables encryption of multiple records in parallel when an async capable crypto accelerator is present in system. This is achieved by allowing the user space application to send more data using sendmsg() even while previously issued data is being processed by crypto accelerator. This requires returning the control back to user space application after submitting encryption request to accelerator. This also means that zero-copy mode of encryption cannot be used with async accelerator as we must be done with user space application buffer before returning from sendmsg(). There can be multiple records in flight to/from the accelerator. Each of the record is represented by 'struct tls_rec'. This is used to store the memory pages for the record. After the records are encrypted, they are added in a linked list called tx_ready_list which contains encrypted tls records sorted as per tls sequence number. The records from tx_ready_list are transmitted using a newly introduced function called tls_tx_records(). The tx_ready_list is polled for any record ready to be transmitted in sendmsg(), sendpage() after initiating encryption of new tls records. This achieves parallel encryption and transmission of records when async accelerator is present. There could be situation when crypto accelerator completes encryption later than polling of tx_ready_list by sendmsg()/sendpage(). Therefore we need a deferred work context to be able to transmit records from tx_ready_list. The deferred work context gets scheduled if applications are not sending much data through the socket. If the applications issue sendmsg()/sendpage() in quick succession, then the scheduling of tx_work_handler gets cancelled as the tx_ready_list would be polled from application's context itself. This saves scheduling overhead of deferred work. The patch also brings some side benefit. We are able to get rid of the concept of CLOSED record. This is because the records once closed are either encrypted and then placed into tx_ready_list or if encryption fails, the socket error is set. This simplifies the kernel tls sendpath. However since tls_device.c is still using macros, accessory functions for CLOSED records have been retained. Signed-off-by:
