2021-10-22iwlwifi: pcie: try to grab NIC access earlyJohannes Berg
Sometimes some NICs may fail to initialize, but if we have such a scenario we may only see an alive timeout (i.e. the firmware doesn't send us the alive message), and that will only cause us to fail the interface up. Try to once grab NIC access during device probe to ensure we can properly talk to the hardware at all, and to do all the potential workarounds in that function. Since we now finish NIC init here, we can remove it from the later potential read of the RF ID.

2021-10-22iwlwifi: mvm: reduce WARN_ON() in TX status pathJohannes Berg
Evidently, it's possible to hit this issue, so reduce the noise from it by just having it print a (rate-limited) message instead. We don't really know yet why we hit it, but there's no value in having a WARN_ON() here.

2021-10-22iwlwifi: allow rate-limited error messagesJohannes Berg
Sometimes we might want to have an error message for something related to TX/RX, but if that somehow happens frequently it'll overwhelm the logs. Add IWL_ERR_LIMIT() to alleviate that by rate-limiting those messages. To do this, rework __iwl_err() a bit to have a mode argument instead of passing yet another (bool) argument to it.

2021-10-22iwlwifi: mvm: remove session protection after auth/assocJohannes Berg
When auth/assoc completes, we should remove session protection, except when association is successful, where we need it until a beacon is received from the AP. In particular, in the case of assoc comeback, currently the session protection event just times out, leading to confusing messages: wlan0: 42:00:00:00:00:00 rejected association temporarily; comeback duration 1000 TU (1024 ms) iwlwifi 0000:00:00.0: Not associated and the session protection is over already... wlan0: Connection to AP 42:00:00:00:00:00 lost wlan0: associate with 42:00:00:00:00:00 (try 2/3) mac80211 never does anything on the "Connection ... lost" as it's not even connected. Removing the session protection when it's no longer needed removes those confusing messages and lets the device do other things in the allocated time.

When having a blank OTP the only way to get the rf id and the cdb info is from prph registers. Currently there is some implementation for this, but it is located in the wrong place in the code (should be before trying to understand what HW is connected and not after), and it has a partial implementation.

ASIX AX88796[1] is a versatile ethernet adapter chip, that can be connected to a CPU with a 8/16-bit bus or with an SPI. This driver supports SPI connection. The driver has been ported from the vendor kernel for ARTIK5[2] boards. Several changes were made to adapt it to the current kernel which include: + updated DT configuration, + clock configuration moved to DT, + new timer, ethtool and gpio APIs, + dev_* instead of pr_* and custom printk() wrappers, + removed awkward vendor power managemtn. + introduced ethtool tunable to control SPI compression [1] https://www.asix.com.tw/products.php?op=pItemdetail&PItemID=104;65;86&PLine=65 [2] https://git.tizen.org/cgit/profile/common/platform/kernel/linux-3.10-artik/ The other ax88796 driver is for NE2000 compatible AX88796L chip. These chips are not compatible. Hence, two separate drivers are required. Signed-off-by: Łukasz Stelmach <l.stelmach@samsung.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-10-21net: enetc: use the skb variable directly in enetc_clean_tx_ring()Vladimir Oltean
The code checks whether the skb had one-step TX timestamping enabled, in order to schedule the work item for emptying the priv->tx_skbs queue. That code checks for "tx_swbd->skb" directly, when we already had a skb retrieved using enetc_tx_swbd_get_skb(tx_swbd) - a TX software BD can also hold an XDP_TX packet or an XDP frame. But since the direct tx_swbd dereference is in an "if" block guarded by the non-NULL quality of "skb", accessing "tx_swbd->skb" directly is not wrong, just confusing. Just use the local variable named "skb". Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Since commit 7294380c5211 ("enetc: support PTP Sync packet one-step timestamping"), we also need "priv" in the larger function scope. So the local variable from the "if" block scope is not needed, and actually shadows the other one. Delete it.

2021-10-21net: enetc: make sure all traffic classes can send large framesVladimir Oltean
The enetc driver does not implement .ndo_change_mtu, instead it configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU] statically to a large value during probe time. The driver used to configure only the max SDU for traffic class 0, and that was fine while the driver could only use traffic class 0. But with the introduction of mqprio, sending a large frame into any other TC than 0 is broken. This patch fixes that by replicating per traffic class the static configuration done in enetc_configure_port_mac().

2021-10-21sfc: Export fibre-specific supported link modesErik Ekman
The 1/10GbaseT modes were set up for cards with SFP+ cages in 3497ed8c852a5 ("sfc: report supported link speeds on SFP connections"). 10GbaseT was likely used since no 10G fibre mode existed. The missing fibre modes for 1/10G were added to ethtool.h in 5711a9822144 ("net: ethtool: add support for 1000BaseX and missing 10G link modes") shortly thereafter. The user guide available at https://support-nic.xilinx.com/wp/drivers lists support for the following cable and transceiver types in section 2.9: - QSFP28 100G Direct Attach Cables - QSFP28 100G SR Optical Transceivers (with SR4 modules listed) - SFP28 25G Direct Attach Cables - SFP28 25G SR Optical Transceivers - QSFP+ 40G Direct Attach Cables - QSFP+ 40G Active Optical Cables - QSFP+ 40G SR4 Optical Transceivers - QSFP+ to SFP+ Breakout Direct Attach Cables - QSFP+ to SFP+ Breakout Active Optical Cables - SFP+ 10G Direct Attach Cables - SFP+ 10G SR Optical Transceivers - SFP+ 10G LR Optical Transceivers - SFP 1000BASE‐T Transceivers - 1G Optical Transceivers (From user guide issue 28.

ADQ provides traffic isolation for application flows in hardware and ability to steer traffic to a given traffic class. This helps in aligning NIC queues to application threads. Traffic classes are configured using mqprio framework of tc command and mapped to HW channels(VSIs) in the driver. The queue set of each traffic class is managed by corresponding VSI. Each traffic channel can be configured with bandwidth rate-limiting limits and is offloaded to the hardware through the mqprio framework by specifying the mode option as 'channel' and shaper option as 'bw_rlimit'. Next, the flows of application can be steered into a given traffic class using "tc filter" command. The option "skip_sw hw_tc x" indicates hw-offload of filtering and steering filtered traffic into specified TC. Non-matching traffic flows through TC0. When channel configuration are removed queue configuration is set to default and filters configured on individual traffic classes are deleted. example: $ ethtool -K eth0 hw-tc-offload on Configure 3 traffic classes and map priority 0,1,2 to TC0, TC1 and TC2 respectively. TC0 has 2 queues from offset 0 & TC1 has 8 queues from offset 2 and TC2 has 4 queues from offset 10. Enable hardware offload of channels. $ tc qdisc add dev eth0 root mqprio num_tc 3 map 0 1 2 queues \ 2@0 8@2 4@10 hw 1 mode channel $ tc qdisc show dev eth0 qdisc mqprio 8001: root tc 2 map 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 0 queues:(0:1) (2:9) (10:13) mode:channel Configure two filters to match based on dst ipaddr, dst tcp port and redirect to TC1 and TC2. $ tc qdisc add dev eth0 clsact $ tc filter add dev eth0 protocol ip ingress prio 1 flower\ dst_ip 192.168.1.1/32 ip_proto tcp dst_port 80\ skip_sw hw_tc 1 $ tc filter add dev eth0 protocol ip ingress prio 1 flower\ dst_ip 192.168.1.1/32 ip_proto tcp dst_port 5001\ skip_sw hw_tc 2 $ tc filter show dev eth0 ingress Delete traffic classes configuration: $ sudo tc qdisc del dev eth0 root ==================== Signed-off-by: David S.

Now that we have a list of struct ocelot_bridge_vlan entries, we can rewrite the pvid logic to simply point to one of those structures, instead of having a separate structure with a "bool valid". The NULL pointer will represent the lack of a bridge pvid (not to be confused with the lack of a hardware pvid on the port, that is present at all times).
