When hdev->tx_sch_mode is HCLGE_FLAG_VNET_BASE_SCH_MODE, the hclge_tm_schd_mode_vnet_base_cfg calls hclge_tm_pri_schd_mode_cfg with vport->vport_id as pri_id, which is used as index for hdev->tm_info.tc_info, it will cause out of bound access issue if vport_id is equal to or larger than HNAE3_MAX_TC. Also hardware only support maximum speed of HCLGE_ETHER_MAX_RATE. So this patch adds two checks for above cases.

Currently when there is share buffer in the SSU(storage switching unit), the low waterline for RX private buffer is too low to keep the hardware running. Hardware may have processed all the packet stored in the private buffer of the low waterline before the new packet comes, because hardware only tell the peer send packet again when the private buffer is under the low waterline. So this patch only allocate RX private buffer if there is enough buffer according to hardware user manual. This patch also reserve some buffer for reusing when TC num is less than or equal to 2, and change PAUSE_TRANS_GAP & HCLGE_NON_DCB_ADDITIONAL_BUF according to hardware user manual.

When change MTU or other operations, which just calling .reset_notify to do HNAE3_DOWN_CLIENT and HNAE3_UP_CLIENT, then the netdev_tx_reset_queue() in the hns3_clear_all_ring() will be ignored. So the dev_watchdog() may misdiagnose a TX timeout. This patch separates netdev_tx_reset_queue() from hns3_clear_all_ring(), and unifies hns3_clear_all_ring() and hns3_force_clear_all_ring into one, since they are doing similar things.

On 32-bit architectures, putting an array of 256 u32 values on the stack uses more space than the warning limit: drivers/net/ethernet/huawei/hinic/hinic_main.c: In function 'hinic_rss_init': drivers/net/ethernet/huawei/hinic/hinic_main.c:286:1: error: the frame size of 1068 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] I considered changing the code to use u8 values here, since that's all the hardware supports, but dynamically allocating the array is a more isolated fix here.

The help text makes it look like NET_VENDOR_CADENCE enables support for Atmel devices, when in reality it's a driver written by Atmel that supports Cadence devices. This may confuse users that have this device on a non-Atmel SoC. The fix is just s/Atmel/Cadence/, but I did go and re-wrap the Kconfig help text as that change caused it to go over 80 characters.

commit c218ad55 ("macb: Add support for SiFive FU540-C000") added a dependency on the common clock framework to the macb driver, but didn't express that dependency in Kconfig. As a result macb now fails to compile on systems without COMMON_CLK, which specifically causes a build failure on powerpc allyesconfig. This patch adds the dependency, which results in the macb driver no longer being selectable on systems without the common clock framework. All known systems that have this device already support the common clock framework, so this should not cause trouble for any uses. Supporting both the FU540-C000 and systems without COMMON_CLK is quite ugly. I've build tested this on powerpc allyesconfig and RISC-V defconfig (which selects MACB), but I have not even booted the resulting kernels.

In configuration of vlan over bridge over aquantia device it was found that vlan tagged traffic is dropped on chip. The reason is that bridge device enables promisc mode, but in atlantic chip vlan filters will still apply. So we have to corellate promisc settings with vlan configuration. The solution is to track in a separate state variable the need of vlan forced promisc. And also consider generic promisc configuration when doing vlan filter config.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct virtchnl_iwarp_qvlist_info { ... struct virtchnl_iwarp_qv_info qv_info[1]; }; size = sizeof(struct virtchnl_iwarp_qvlist_info) + (sizeof(struct virtchnl_iwarp_qv_info) * count; instance = kzalloc(size, GFP_KERNEL); and struct virtchnl_vf_resource { ... struct virtchnl_vsi_resource vsi_res[1]; }; size = sizeof(struct virtchnl_vf_resource) + sizeof(struct virtchnl_vsi_resource) * count; instance = kzalloc(size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, qv_info, count), GFP_KERNEL); and instance = kzalloc(struct_size(instance, vsi_res, count), GFP_KERNEL); Notice that, in the first case above, variable size is not necessary, hence it is removed.

Changing descriptor count via 'ethtool -G' is not persistent across resets. When PF reset occurs, we roll back to the default value of vsi->num_desc, which is used then in i40e_alloc_rings to set descriptor count. XDP does a PF reset so when user has changed the descriptor count and load XDP program, the default count will be back there. To fix this: * introduce new VSI members - num_tx_desc and num_rx_desc in favour of num_desc * set them in i40e_set_ringparam to user's values * set them to default values in i40e_set_num_rings_in_vsi only when they don't have previous values Signed-off-by: NMaciej Fijalkowski <maciej.fijalkowski@intel.com> Tested-by: NAndrew Bowers <andrewx.bowers@intel.com> Signed-off-by: NJeff Kirsher <jeffrey.t.kirsher@intel.com>

This patch fixes reading f/w LLDP agent status at DCB init time. It's done by removing direct NVM reading in i40e_update_dcb_config() and checking whether f/w LLDP agent is disabled via I40E_FLAG_DISABLE_FW_LLDP flag in i40e_init_pf_dcb(). The function i40e_update_dcb_config() in i40e_main.c is a temporary solution which will be later renamed to i40e_init_dcb() in the i40e_dcb module. Also logging was extended to make visible if f/w LLDP agent is running or not and always log a message when DCB was not initialized. Without this patch for new f/w versions f/w LLDP agent status was always read from NVM as disabled and DCB initialization failed without clear reason in logs.
