During HW scan, the channel related feilds in hal struct changed partially. If setting Tx power will get WARNING:rtw_get_tx_power_params() due to some of fields in hal struct mismatch. Therefore, we fix to change all required fields in hal struct when channel switch during HW scan. Signed-off-by:

The skb will be allocated to send TIM update info in brcmf_fws_tim_update. Currently the skb will be freed when tx is failed but it will not be freed when tx is completed successfully. The fix is to free the skb when tx is completed always. Signed-off-by:

The race condition in brcmf_msgbuf_txflow and brcmf_msgbuf_delete_flowring makes tx_msghdr writing after brcmf_msgbuf_remove_flowring. Host driver should delete flowring after txflow complete and all txstatus back, or pend_8021x_cnt will never be zero and cause every connection 950 milliseconds(MAX_WAIT_FOR_8021X_TX) delay.

Since IQK could spend time, we make a cache of IQK result matrix that looks like iqk_matrix[channel_idx].val[x][y], and we can reload the matrix if we have made a cache. To determine a cache is made, we check iqk_matrix[channel_idx].val[0][0]. The initial commit 7274a8c2 ("rtlwifi: rtl8192de: Merge phy routines") make a mistake that checks incorrect iqk_matrix[channel_idx].val[0] that is always true, and this mistake is found by commit ee3db469 ("wifi: rtlwifi: remove always-true condition pointed out by GCC 12"), so I recall the vendor driver to find fix and apply the correctness.

Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS. Signed-off-by:

The original timing that store OP channel info is after associated. However, HW scan might happen before associated without backing to OP channel, that will cause authentication or association fail. Therefore, we modify the timing of storing OP channel info. Signed-off-by:

Chih-Kang Chang authored
HW scan need to start queues after switch to OP channel, and stop queues before leaving op channel. However, in original code, driver will start queues after switch to OP channel, but stop queues until switch to OP channel next time, that will cause packets transmitted in wrong channel. So we fix the stop queues timing. Signed-off-by:

Representors do not want to be subject to the PF's Ethernet address filters, since traffic from VFs will typically have a destination either elsewhere on the link segment or on an overlay network. So, create a dynamic m-port with promiscuous and all-multicast filters, and set it as the egress port of representor default rules. Since the m-port is an alias of the calling PF's own m-port, traffic will still be delivered to the PF's RXQs, but it will be subject to the VNRX filter rules installed on the dynamic m-port (specified by the v-port ID field of the filter spec).

We need to be able to drop the efx->filter_sem in ef100_filter_table_up() so that we can call functions that insert filters (and thus take that rwsem for read), which means the efx->type->filter_table_probe method needs to be responsible for taking the lock in the first place. Signed-off-by:

Edward Cree authored
Default rules are low-priority switching rules which the hardware uses in the absence of higher-priority rules. Each representor requires a corresponding rule matching traffic from its representee VF and delivering to the PF (where a check on INGRESS_MPORT in __ef100_rx_packet() will direct it to the representor). No rule is required in the reverse direction, because representor TX uses a TX override descriptor to bypass the MAE and deliver directly to the VF. Since inserting any rule into the MAE disables the firmware's own default rules, also insert a pair of rules to connect the PF to the physical network port and vice-versa. Signed-off-by:

If not, for now drop them and warn. A subsequent patch will look up the source m-port to try and find a representor to deliver them to. Signed-off-by:

Edward Cree authored
Traffic delivered to the (MAE admin) PF could be from either the wire or a VF. The INGRESS_MPORT field of the RX prefix distinguishes these; base_mport is the value this field will have for traffic from the wire (which should be delivered to the PF's netdevice, not a representor). Signed-off-by:

Edward Cree authored
Representor RX uses a NAPI context driven by a 'fake interrupt': when the parent PF receives a packet destined for the representor, it adds it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake interrupt' is primed. The NAPI poll then pulls packets off this list and feeds them to the stack with netif_receive_skb_list(). This scheme allows us to decouple representor RX from the parent PF's RX fast-path. This patch implements the 'top half', which builds an SKB, copies data into it from the RX buffer (which can then be released), adds it to the queue and fires the 'fake interrupt' if necessary. Signed-off-by:

This patch adds the 'bottom half' napi->poll routine for representor RX. See the next patch (with the top half) for an explanation of the 'fake interrupt' scheme used to drive this NAPI context. Signed-off-by:
