2020-08-20nfp: flower: add support to offload QinQ matchLouis Peens4-16/+152
When both the driver and the firmware supports QinQ the flow key structure that is send to the firmware is updated as the old method of matching on VLAN did not allow for space to add another VLAN tag. VLAN flows can now also match on the tpid field, not constrained to just 0x8100 as before.

2020-08-19ibmvnic: store RX and TX subCRQ handle array in ibmvnic_adapter structCristobal Forno2-12/+27
Currently the driver reads RX and TX subCRQ handle array directly from a DMA-mapped buffer address when it needs to make a H_SEND_SUBCRQ hcall. This patch stores that information in the ibmvnic_sub_crq_queue structure instead of reading from the buffer received at login. The overall goal of this patch is to parse relevant information from the login response buffer and store it in the driver's private data structures so that we don't need to read directly from the buffer and can then free up that memory.

2020-08-19r8169: remove member irq_enabled from struct rtl8169_privateHeiner Kallweit1-5/+1
After making use of the gro_flush_timeout attribute I once got a tx timeout due to an interrupt that wasn't handled. Seems using irq_enabled can be racy, and it's not needed any longer anyway, so remove it. I've never seen a report about such a race before, therefore treat the change as an improvement. There's just one small drawback: If a legacy PCI interrupt is used, and if this interrupt is shared with a device with high interrupt rate, then we may handle interrupts even if NAPI disabled them, and we may see a certain performance decrease under high network load.

2020-08-16bonding: fix a potential double-unregisterCong Wang1-1/+2
When we tear down a network namespace, we unregister all the netdevices within it. So we may queue a slave device and a bonding device together in the same unregister queue. If the only slave device is non-ethernet, it would automatically unregister the bonding device as well. Thus, we may end up unregistering the bonding device twice. Workaround this special case by checking reg_state.

2020-08-14drivers/net/wan/hdlc_x25: Added needed_headroom and a skb->len checkXie He2-1/+17
1. Added a skb->len check This driver expects upper layers to include a pseudo header of 1 byte when passing down a skb for transmission. This driver will read this 1-byte header. This patch added a skb->len check before reading the header to make sure the header exists. 2. Added needed_headroom and set hard_header_len to 0 When this driver transmits data, first this driver will remove a pseudo header of 1 byte, then the lapb module will prepend the LAPB header of 2 or 3 bytes. So the value of needed_headroom in this driver should be 3 - 1. Because this driver has no header_ops, according to the logic of af_packet.c, the value of hard_header_len should be 0. Reason of setting needed_headroom and hard_header_len at this place: This driver is written using the API of the hdlc module, the hdlc module enables this driver (the protocol driver) to run on any hardware that has a driver (the hardware driver) written using the API of the hdlc module. Two other hdlc protocol drivers - hdlc_ppp and hdlc_raw_eth, also set things like hard_header_len at this place. In hdlc_ppp, it sets hard_header_len after attach_hdlc_protocol and before setting dev->type. In hdlc_raw_eth, it sets hard_header_len by calling ether_setup after attach_hdlc_protocol and after memcpy the settings. 3. Reset needed_headroom when detaching protocols (in hdlc.c) When detaching a protocol from a hardware device, the hdlc module will reset various parameters of the device (including hard_header_len) to the default values. We add needed_headroom here so that needed_headroom will also be reset.

2020-08-14bonding: show saner speed for broadcast modeJarod Wilson1-3/+18
Broadcast mode bonds transmit a copy of all traffic simultaneously out of all interfaces, so the "speed" of the bond isn't really the aggregate of all interfaces, but rather, the speed of the slowest active interface. Also, the type of the speed field is u32, not unsigned long, so adjust that accordingly, as required to make min() function here without complaining about mismatching types.
