The maximum number of ports is actually 11, according to two observations: 1. The highest port ID used in the vendor driver is 10. Since port IDs are indexed from 0, and since DSA follows the same numbering system, this means up to 11 ports are to be presumed. 2. The registers with port mask fields always amount to a maximum port mask of 0x7FF, corresponding to a maximum 11 ports. In view of this, I also deleted the comment. Signed-off-by:

Alex Elder says: ==================== net: ipa: more multi-channel event ring work This series makes a little more progress toward supporting multiple channels with a single event ring. The first removes the assumption that consecutive events are associated with the same RX channel. The second derives the channel associated with an event from the event itself, and the next does a small cleanup enabled by that. The fourth causes updates to occur for every event processed (rather once). And the final patch does a little more rework to make TX completion have more in common with RX completion. ==================== Link: https://lore.kernel.org/r/20220615165929.5924-1-elder@linaro.orgSigned-off-by:

Move the processing done for TX channels in gsi_channel_update() into gsi_evt_ring_rx_update(). The called function is called for both RX and TX channels, so rename it to be gsi_evt_ring_update(). As a result, this code no longer assumes events in an event ring are associated with just one channel. Because all events in a ring are handled in that function, we can move the call to gsi_trans_move_complete() there, and can ring the event ring doorbell there as well after all new events in the ring have been processed.

When an RX transaction completes, we update the trans->len field to contain the actual number of bytes received. This is done in a loop in gsi_evt_ring_rx_update(). Change that function so it checks the data transfer direction recorded in the transaction, and only updates trans->len for RX transfers. Then call it unconditionally. This means events for TX endpoints will run through the loop without otherwise doing anything, but this will change shortly. Signed-off-by:

The only reason the event ring's channel pointer is needed in gsi_evt_ring_rx_update() is so we can get at its GSI pointer. We can pass the GSI pointer as an argument, along with the event ring ID, and thereby avoid using the event ring channel pointer. This is another step toward no longer assuming an event ring services a single channel. Signed-off-by:

Change gsi_channel_trans_map() so it derives the channel used from the transaction. Pass the index of the *first* TRE used by the transaction, and have the called function account for the fact that the last one used is what's important. Signed-off-by:

Alex Elder authored
In gsi_evt_ring_rx_update(), use gsi_event_trans() repeatedly to find the transaction associated with an event, rather than assuming consecutive events are associated with the same channel. This removes the only caller of gsi_trans_pool_next(), so get rid of it. Signed-off-by:

Rasmus Villemoes says: ==================== dt-bindings: dp83867: add binding for io_impedance_ctrl nvmem cell We have a board where measurements indicate that the current three options - leaving IO_IMPEDANCE_CTRL at the reset value (which is factory calibrated to a value corresponding to approximately 50 ohms) or using one of the two boolean properties to set it to the min/max value - are too coarse.

There is no fixed mapping from register values to values in the range 35-70 ohms; it varies from chip to chip, and even that target range is approximate. So add a DT binding for an nvmem cell which can be populated during production with a value suitable for each specific board. Reviewed-by:

The extra byte inserted by usbnet.c when (length % dev->maxpacket == 0) is causing problems to device. This patch sets FLAG_SEND_ZLP to avoid this. Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet Problems observed: ====================================================================== 1) Using ssh/sshfs. The remote sshd daemon can abort with the message: "message authentication code incorrect" This happens because the tcp message sent is corrupted during the USB "Bulk out". The device calculate the tcp checksum and send a valid tcp message to the remote sshd. Then the encryption detects the error and aborts. 2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out 3) Stop normal work without any log message. The "Bulk in" continue receiving packets normally. The host sends "Bulk out" and the device responds with -ECONNRESET. (The netusb.c code tx_complete ignore -ECONNRESET) Under normal conditions these errors take days to happen and in intense usage take hours. A test with ping gives packet loss, showing that something is wrong: ping -4 -s 462 {destination} # 462 = 512 - 42 - 8 Not all packets fail. My guess is that the device tries to find another packet starting at the extra byte and will fail or not depending on the next bytes (old buffer content). ====================================================================== Signed-off-by:Jose Alonso <joalonsof@gmail.com> Signed-off-by:
