When wiphy dumps cannot be split, such as in events or with older userspace that doesn't support it, the size can today be too big. Reduce it, by doing two things: 1) remove data that couldn't have been present before the split capability was introduced since it's new, such as HE capabilities 2) as suggested by Martin Willi, remove management frame subtypes from the split dumps, as just (1) isn't even enough due to other new code capabilities. This is fine as old consumers (really just wpa_supplicant) didn't check this data before they got support for split dumps. Reported-by:Martin Willi <martin@strongswan.org> Suggested-by:

Allow drivers to request that interface-iterator does NOT iterate over interfaces that are not sdata-in-driver. This will allow us to fix crashes in ath10k (and possibly other drivers). To summarize Johannes' explanation: Consider add interface wlan0 add interface wlan1 iterate active interfaces -> wlan0 wlan1 add interface wlan2 iterate active interfaces -> wlan0 wlan1 wlan2 If you apply this scenario to a restart, which ought to be functionally equivalent to the normal startup, just compressed in time, you're basically saying that today you get add interface wlan0 add interface wlan1 iterate active interfaces -> wlan0 wlan1 wlan2 << problem here add interface wlan2 iterate active interfaces -> wlan0 wlan1 wlan2 which yeah, totally seems wrong. But fixing that to be add interface wlan0 add interface wlan1 iterate active interfaces -> <nothing> add interface wlan2 iterate active interfaces -> <nothing> (or maybe -> wlan0 wlan1 wlan2 if the reconfig already completed) This is also at least somewhat wrong, but better to not iterate over something that exists in the driver than iterate over something that does not. Originally the first issue was causing crashes in testing with lots of station vdevs on an ath10k radio, combined with firmware crashing. I ran with a similar patch for years with no obvious bad results, including significant testing with ath9k and ath10k. Signed-off-by:

The SRG min and max offset won't present when SRG Information Present of SR control field of Spatial Reuse Parameter Set element set to 0. Per spec. IEEE802.11ax D7.0, SRG OBSS PD Min Offset ≤ SRG OBSS PD Max Offset. Hence fix the constrain check to allow same values in both offset and also call appropriate nla_get function to read the values.

The the __freq_reg_info() never returns NULL and the callers don't check for NULL. This initialization to set "reg_rule = NULL;" is just there to make GCC happy but it's not required in current GCCs. The problem is that Smatch sees the initialization and concludes that this function can return NULL so it complains that the callers are not checking for it. Smatch used to be able to parse this correctly but we recently changed the code from: - for (bw = MHZ_TO_KHZ(20); bw >= min_bw; bw = bw / 2) { + for (bw = MHZ_TO_KHZ(bws[i]); bw >= min_bw; bw = MHZ_TO_KHZ(bws[i--])) { Originally Smatch used to understand that this code always iterates through the loop once, but the change from "MHZ_TO_KHZ(20)" to "MHZ_TO_KHZ(bws[i])" is too complicated for Smatch.

S1G doesn't have legacy (sband->bitrates) rates, only MCS. For now, just send a frame at MCS 0 if a low rate is requested. Note we also redefine (since we're out of TX flags) TX_RC_VHT_MCS as TX_RC_S1G_MCS to indicate an S1G MCS. This is probably OK as VHT MCS is not valid on S1G band and vice versa. Signed-off-by:

S1G allows listen interval up to 2^14 * 10000 beacon intervals. In order to do this listen interval needs a scaling factor applied to the lower 14 bits. Calculate this and properly encode the listen interval for S1G STAs. See IEEE802.11ah-2016 Table 9-44a for reference. Signed-off-by:

The S1G beacon is an extension frame as opposed to management frame for the regular beacon. This means we may have to occasionally cast the frame buffer to a different header type. Luckily this isn't too bad as scan results mostly only care about the IEs. Signed-off-by:

Because we can miss AP wakeup (beacon) while scanning other channels, it's better go into wakeup state and inform the AP of that upon returning to the operating channel, rather than staying asleep and waiting for the next TIM indicating traffic for us. This saves precious time, especially when we only have 200ms inter- scan period for monitoring the active connection. Signed-off-by:

Michael Chan says: ==================== bnxt_en: Update for net-next. This patch series adds 2 main features to the bnxt_en driver: 200G link speed support and FEC support with some refactoring of the link speed logic. The firmware interface is updated to have proper support for these 2 features. The ethtool preset max channel value is also adjusted properly to account for XDP and TCs. ==================== Signed-off-by: -
Michael Chan authored
The current logic that calculates the preset maximum value for combined channel does not take into account the rings used for XDP and mqprio TCs. Each of these features will reduce the number of TX rings. Add the logic to divide the TX rings accordingly based on whether the device is currently in XDP mode and whether TCs are in use.

PORT_PHY_CONFIG is always sent with REQ_FLAGS_RESET_PHY set. This flag must be set in order for the firmware to institute the requested PHY change immediately, but it results in a link flap. This is unnecessary and results in an improved user experience if the PHY reconfiguration is avoided when the user requested speed does not constitute a change. Signed-off-by:

On some 200G dual port NICs, if one port is configured to 200G, firmware will disable the ethernet link on the other port. Firmware will send notification to the driver for the disabled port when this happens. Define a new field in the link_info structure to keep track of this state. The new phy_state field replaces the unused loop_back field. Log a message when the phy_state changes state. In the disabled state, disallow any PHY configurations on the disabled port as the firmware will fail all calls to configure the PHY in this state. Reviewed-by:

The firmware interface has added support for new link speeds using PAM4 modulation. Expand the bnxt_link_info structure to closely mirror the new firmware structures. Add logic to copy the PAM4 capabilities and settings from the firmware. Signed-off-by:
-
Edwin Peer authored
It will be necessary to update more than one field in the link_info structure when PAM4 speeds are added in a later patch. Instead of merely translating ethtool speed values to firmware speed values, change the responsiblity of this function to update all the necessary link_info fields required to force the speed change to the desired ethtool value. This also reduces code duplication somewhat at the two call sites, which otherwise both have to independently update link_info fields to turn off auto negotiation advertisements. Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen to have the same values, but req_link_speed is utilimately passed as force_link_speed in HWRM_PORT_PHY_CFG which is not defined in terms of REQ_AUTO_LINK_SPEED. Reviewed-by:
