NPC extraction profile marks layer types NPC_LT_LB_CTAG for CTAG and NPC_LT_LB_STAG_QINQ for STAG after parsing input packet. Those layer types can be used to install ntuple filters using vlan-etype option. Below are the commands and corresponding behavior with this patch in place. > alias nt "ethtool -U eth0 flow-type ether" > nt vlan 5 m 0xf000 action 0 Input packets with outer VLAN id as 5 i.e, stag packets with VLAN id 5 and ctag packets with VLAN id as 5 are hit. > nt vlan-etype 0x8100 action 0 All input ctag packets with any VLAN id are hit. > nt vlan-etype 0x88A8 action 0 All input stag packets with any VLAN id are hit. > nt vlan-etype 0x8100 vlan 5 m 0xf000 action 0 All input ctag packets with VLAN id 5 are hit. > nt vlan-etype 0x88A8 vlan 5 m 0xf000 action 0 All input stag packets with VLAN id 5 are hit.

queue Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2021-08-27 ravindhan Gunasekaran says: This adds support for Credit-based shaper qdisc offload from Traffic Control system. It enables traffic prioritization and bandwidth reservation via the Credit-Based Shaper which is implemented in hardware by i225 controller. Patch 1/3 adds a default cycle-time for TSN mode to be configured. Patch 2/3 helps to separate TSN mode programming on the fly and during reset sequence. It also simplifies handling features flags for various TSN modes supported by i225 in the driver. Patch 3/3 adds support for IEEE802.1Qav(CBS) standard implemented in i225 HW. Two sets of CBS HW shapers are present in i225 and driver enables them in the two high priority queues. ==================== Signed-off-by:

In some cases of fw_down it was called because there was a fw_generation change, and the firmware is already back up. In order to keep the down time to a minimum, don't wait for the next watchdog polling cycle, fire another watchdog off as soon as we can - an out-of-cycle check won't hurt, and may well speed up the recovery.

The kernel provides a "/proc/sys/net/ipv6/conf/<iface>/mtu" file, which can temporarily record the mtu value of the last received RA message when the RA mtu value is lower than the interface mtu, but this proc has following limitations: (1) when the interface mtu (/sys/class/net/<iface>/mtu) is updeated, mtu6 (/proc/sys/net/ipv6/conf/<iface>/mtu) will be updated to the value of interface mtu; (2) mtu6 (/proc/sys/net/ipv6/conf/<iface>/mtu) only affect ipv6 connection, and not affect ipv4. Therefore, when the mtu option is carried in the RA message, there will be a problem that the user sometimes cannot obtain RA mtu value correctly by reading mtu6. After this patch set, if a RA message carries the mtu option, you can send a netlink msg which nlmsg_type is RTM_GETLINK, and then by parsing the attribute of IFLA_INET6_RA_MTU to get the mtu value carried in the RA message received on the inet6 device. In addition, you can also get a link notification when ra_mtu is updated so it doesn't have to poll. In this way, if the MTU values that the device receives from the network in the PCO IPv4 and the RA IPv6 procedures are different, the user can obtain the correct ipv6 ra_mtu value and compare the value of ra_mtu and ipv4 mtu, then the device can use the lower MTU value for both IPv4 and IPv6.

bnxt may discard packets if Rx completions are consumed in an attempt to let netpoll make progress. It should be extremely rare in practice but nonetheless such events should be counted. Since completion ring memory is allocated dynamically use a similar scheme to what is done for HW stats to save them. Report the stats in rx_dropped and per-netdev ethtool counter. Chances that users care which ring dropped are very low. v3: only save the stat to rx_dropped on reset, rx_total_netpoll_discards will now only show drops since last reset, similar to other "total_discard" counters.

Implement support for Credit-based shaper(CBS) Qdisc hardware offload mode in the driver. There are two sets of IEEE802.1Qav (CBS) HW logic in i225 controller and this patch supports enabling them in the top two priority TX queues. Driver implemented as recommended by Foxville External Architecture Specification v0.993. Idleslope and Hi-credit are the CBS tunable parameters for i225 NIC, programmed in TQAVCC and TQAVHC registers respectively. In-order for IEEE802.1Qav (CBS) algorithm to work as intended and provide BW reservation CBS should be enabled in highest priority queue first. If we enable CBS on any of low priority queues, the traffic in high priority queue does not allow low priority queue to be selected for transmission and bandwidth reservation is not guaranteed.

Separates the procedure done during reset from applying a configuration, knowing when the code is executing allow us to separate the better what changes the hardware state from what changes only the driver state. Introduces a flag for bookkeeping the driver state of TSN features. When Qav and frame-preemption is also implemented this flag makes it easier to keep track on whether a TSN feature driver state is enabled or not though controller state changes, say, during a reset.

Sets default values for each queue cycle start and cycle end. This allows some simplification in the handling of these configurations as most TSN features in i225 require a cycle to be configured. In i225, cycle start and end time is required to be programmed for CBS to work properly. Signed-off-by:
