2023-04-13wifi: ieee80211: correctly mark FTM frames non-bufferableJohannes Berg
The checks of whether or not a frame is bufferable were not taking into account that some action frames aren't, such as FTM. Check this, which requires some changes to the function ieee80211_is_bufferable_mmpdu() since we need the whole skb for the checks now.

2023-04-13net: enetc: workaround for unresponsive pMAC after receiving express trafficVladimir Oltean
I have observed an issue where the RX direction of the LS1028A ENETC pMAC seems unresponsive. The minimal procedure to reproduce the issue is: 1. Connect ENETC port 0 with a loopback RJ45 cable to one of the Felix switch ports (0). 2. Bring the ports up (MAC Merge layer is not enabled on either end). 3. Send a large quantity of unidirectional (express) traffic from Felix to ENETC. I tried altering frame size and frame count, and it doesn't appear to be specific to either of them, but rather, to the quantity of octets received. Lowering the frame count, the minimum quantity of packets to reproduce relatively consistently seems to be around 37000 frames at 1514 octets (w/o FCS) each. 4. Using ethtool --set-mm, enable the pMAC in the Felix and in the ENETC ports, in both RX and TX directions, and with verification on both ends. 5. Wait for verification to complete on both sides. 6. Configure a traffic class as preemptible on both ends. 7. Send some packets again. The issue is at step 5, where the verification process of ENETC ends (meaning that Felix responds with an SMD-R and ENETC sees the response), but the verification process of Felix never ends (it remains VERIFYING). If step 3 is skipped or if ENETC receives less traffic than approximately that threshold, the test runs all the way through (verification succeeds on both ends, preemptible traffic passes fine). If, between step 4 and 5, the step below is also introduced: 4.1. Disable and re-enable PM0_COMMAND_CONFIG bit RX_EN then again, the sequence of steps runs all the way through, and verification succeeds, even if there was the previous RX traffic injected into ENETC. Traffic sent *by* the ENETC port prior to enabling the MAC Merge layer does not seem to influence the verification result, only received traffic does. The LS1028A manual does not mention any relationship between PM0_COMMAND_CONFIG and MMCSR, and the hardware people don't seem to know for now either. The bit that is toggled to work around the issue is also toggled by enetc_mac_enable(), called from phylink's mac_link_down() and mac_link_up() methods - which is how the workaround was found: verification would work after a link down/up.

2023-04-13bnxt_en: Allow to set switchdev mode without existing VFsIvan Vecera
Remove an inability of bnxt_en driver to set eswitch to switchdev mode without existing VFs by: 1. Allow to set switchdev mode in bnxt_dl_eswitch_mode_set() so representors are created only when num_vfs > 0 otherwise just set bp->eswitch_mode 2. Do not automatically change bp->eswitch_mode during bnxt_vf_reps_create() and bnxt_vf_reps_destroy() calls so the eswitch mode is managed only by an user by devlink. Just set temporarily bp->eswitch_mode to legacy to avoid re-opening of representors during destroy. 3. Create representors in bnxt_sriov_enable() if current eswitch mode is switchdev one Tested by this sequence: 1. Set PF interface up 2. Set PF's eswitch mode to switchdev 3. Created N VFs 4. Checked that N representors were created 5. Set eswitch mode to legacy 6. Checked that representors were deleted 7. Set eswitch mode back to switchdev 8. Checked that representors exist again for VFs 9. Deleted all VFs 10. Checked that all representors were deleted as well 11.

2023-04-12wifi: rtw88: main: Reserve 8 bytes of extra TX headroom for SDIO cardsMartin Blumenstingl
For SDIO host controllers with DMA support the TX buffer physical memory address need to be aligned at an 8-byte boundary. Reserve 8 bytes of extra TX headroom so we can align the data without re-allocating the transmit buffer. While here, also remove the TODO comment regarding extra headroom for USB and SDIO. For SDIO the extra headroom is now handled and for USB it was not needed so far.

2023-04-12wifi: rtw88: sdio: Add HCI implementation for SDIO based chipsetsMartin Blumenstingl
Add a sub-driver for SDIO based chipsets which implements the following functionality: - register accessors for 8, 16 and 32 bits for all states of the card (including usage of 4x 8 bit access for one 32 bit buffer if the card is not fully powered on yet - or if it's fully powered on then 1x 32 bit access is used) - checking whether there's space in the TX FIFO queue to transmit data - transfers from the host to the device for actual network traffic, reserved pages (for firmware download) and H2C (host-to-card) transfers - receiving data from the device - deep power saving state The transmit path is optimized so DMA-capable SDIO host controllers can directly use the buffers provided because the buffer's physical addresses are 8 byte aligned. The receive path is prepared to support RX aggregation where the chipset combines multiple MAC frames into one bigger buffer to reduce SDIO transfer overhead.

2023-04-12wifi: rtw88: Clear RTW_FLAG_POWERON early in rtw_mac_power_switch()Martin Blumenstingl
The SDIO HCI implementation needs to know when the MAC is powered on. This is needed because 32-bit register access has to be split into 4x 8-bit register access when the MAC is not fully powered on or while powering off. When the MAC is powered on 32-bit register access can be used to reduce the number of transfers but splitting into 4x 8-bit register access still works in that case. During the power on sequence is how RTW_FLAG_POWERON is only set when the power on sequence has completed successfully. During power off however RTW_FLAG_POWERON is set. This means that the upcoming SDIO HCI implementation does not know that it has to use 4x 8-bit register accessors. Clear the RTW_FLAG_POWERON flag early when powering off the MAC so the whole power off sequence is processed with RTW_FLAG_POWERON unset. This will make it possible to use the RTW_FLAG_POWERON flag in the upcoming SDIO HCI implementation. Note that a failure in rtw_pwr_seq_parser() while applying chip->pwr_off_seq can theoretically result in the RTW_FLAG_POWERON flag being cleared while the chip is still powered on. However, depending on when the failure occurs in the power off sequence the chip may be on or off. Even the original approach of clearing RTW_FLAG_POWERON only when the power off sequence has been applied successfully could end up in some corner case where the chip is powered off but RTW_FLAG_POWERON was not cleared.
