Define new netlink attributes for rmnet mux_id and flags. These flags / mux_id were earlier using vlan flags / id respectively. The flag bits are also moved to uapi and are renamed with prefix RMNET_FLAG_*. Also add the rmnet policy to handle the new netlink attributes. Signed-off-by:

The current logic of flags | TUNNEL_SEQ is always non-zero and hence sequence numbers are always incremented no matter the setting of the TUNNEL_SEQ bit. Fix this by using & instead of |.

GhantaKrishnamurthy MohanKrishna says: ==================== tipc: socket diagnostics additions for AF_TIPC The following patchsets add socket diagnostics support for AF_TIPC by using the sock diag framework. The patchset was created on top of commit id: fb66cb07. New iproute2 package is needed to use this functionality which will be sent for review in a seperate mail. The commit series improves diagnosis of tipc sockets by exporting the configuration, states and statistics of sockets. The series has been co-authored by Parthasarathy Bhuvaragan and consist of two parts: 1-2: Adaptations of existing code to support sock_diag framework. We modify existing functions to support socket diagnostics. Required information about the sockets are exported. 3: Step sk_drops during packet drop. This occurs if the packet cannot be queued due to queue length exceeding configured thresholds. The diag module is optional, and if enabled it will be loaded on demand when needed. ==================== Signed-off-by:

Currently when tipc is unable to queue a received message on a socket, the message is rejected back to the sender with error TIPC_ERR_OVERLOAD. However, the application on this socket has no knowledge about these discards. In this commit, we try to step the sk_drops counter when tipc is unable to queue a received message. Export sk_drops using tipc socket diagnostics. Acked-by:

This commit adds socket diagnostics capability for AF_TIPC in netlink family NETLINK_SOCK_DIAG in a new kernel module (diag.ko). The following are key design considerations: - config TIPC_DIAG has default y, like INET_DIAG. - only requests with flag NLM_F_DUMP is supported (dump all). - tipc_sock_diag_req message is introduced to send filter parameters. - the response attributes are of TLV, some nested. To avoid exposing data structures between diag and tipc modules and avoid code duplication, the following additions are required: - export tipc_nl_sk_walk function to reuse socket iterator. - export tipc_sk_fill_sock_diag to fill the tipc diag attributes. - create a sock_diag response message in __tipc_add_sock_diag defined in diag.c and use the above exported tipc_sk_fill_sock_diag to fill response.

The current socket iterator function tipc_nl_sk_dump, handles socket locks and calls __tipc_nl_add_sk for each socket. To reuse this logic in sock_diag implementation, we do minor modifications to make these functions generic as described below. In this commit, we add a two new functions __tipc_nl_sk_walk, __tipc_nl_add_sk_info and modify tipc_nl_sk_dump, __tipc_nl_add_sk accordingly. In __tipc_nl_sk_walk we: 1. acquire and release socket locks 2. for each socket, execute the specified callback function In __tipc_nl_add_sk we: - Move the netlink attribute insertion to __tipc_nl_add_sk_info. tipc_nl_sk_dump calls tipc_nl_sk_walk with __tipc_nl_add_sk as argument. sock_diag will use these generic functions in a later commit. There is no functional change in this commit. Acked-by:

Tal Bar authored
In 'auto-neg off' the device have sent AN (auto-negotiation) frames with the forced speed. Thus, fix it using an_disable_admin field in Port type and speed (PTYS) register. This field indicates if speed negotiation frames would be send by the port or not. Add the field and enable/disable it for 'auto-neg on/off', make the port to start/stop sending AN (auto-negotiation) frames. Note that for SwitchX2 the behavior doesn't change (i.e support only AN enabled with forced speed). Signed-off-by:

Since we change the update rate of int_gl from every interrupt to every one hundred interrupts, the old way to get time interval by int_gl value is not accurate. This patch calculates the time interval using the jiffies value. Signed-off-by:

Fuyun Liang authored
The interrupt coalescing self-adaptive function updates the int_gl every interrupt. The GL update rate is too faster to get a better new GL value. This patch changes the GL update rate to every one hundred interrupts. The GL update rate is defined by HNS3_INT_ADAPT_DOWN_START. Signed-off-by:

It may need more time for IMP handle some command, such as reset. This patch enlarges the max time for cmd timeout. Driver will check the IMP result every us, it may break through the loop when get the right result. So not all command need the max time. Signed-off-by:

There is no module that is dependent on hclge or hclgevf's symbol, but hns_enet need them to provide ops for it to run. When there is a need to auto load the hns3 driver, the auto load will fail because hclge or hclgevf is not loaded. Hns_enet has already exported the pci table, so this patch exports the pci table for hclge and hclgevf module too. Signed-off-by:

VF queue reset flow is different from PF queue reset flow. VF driver should stop VF queue first, then send message to PF and PF do the reset. PF should send a response to VF after PF complete the queue reset, VF can initialize the queue hw after get the response. This patch fixes the VF queue reset flow as the correct step. Signed-off-by:

When changing the mtu, the max frame size also will be changed. The tx buffer size and the rx buffer size to be allocated are determined by max frame size. So when max frame size is changed, the tx buffer and rx buffer need to be reallocated. When the tc_num is changed, the tx buffer and rx buffer need to be reallocated too. So calling set_mtu and buffer_alloc separately is better. Signed-off-by:
