* rtwn/usb: add ID for D-Link DWA-121 rev B1 to rtwn RTL8188EUBjoern A. Zeeb2026-05-301-0/+1
| | | | | | | | | | Add the device ID to the usbdevs table in order to be able to use it in the rtwn/usb driver for the RTL8188EU attachment. (I adjusted the name to B1 compared to the original submission) PR: 291839 MFC after: 3 days
* rtwn: fix mbuf allocation errors in USB RX path for > 4 KiB framesAdrian Chadd2025-05-011-3/+8
| | | | | | | | | | | | | | | | | We can and do receive > 4 KiB frames in the RX path (A-MSDU frames can be up to 11KiB.) At least one user has reported seeing this and having it break their traffic flows. Use m_get3() to try and grab an mbuf jumbo cluster. This may not be the best permanent solution, but it at least will fail for frame sizes we expect to see up and including the largest A-MPDU frame (11Kib) and keep a counter if it can't allocate, versus just returning NULL because it's too large (and not keeping counters.)

* rtwn: add placeholder for the per-MACID rate reportAdrian Chadd2024-12-071-0/+21
| | | | | | | | | | | | | | Some chipsets (such as the RTL8188E) have firmware which supports a second kind of TX report - instead of a per-packet TX report, it can generate a per-MACID summary of packet success/failure counters. This would be helpful for those chips to cut back on the USB traffic to get rate control feedback for the driver based rate control we're currently using. This is a no-op; it just gets the pieces in place for future work. Differential Revision: https://reviews.freebsd.org/D47894

* rtwn: change the USB TX transfers to only do one pending transfer per endpointAdrian Chadd2024-11-215-38/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found I was getting constant device timeouts when doing anything more complicated than a single SSH on laptop with RTL8811AU. After digging into it, i found a variety of fun situations, including traffic stalls that would recover w/ a shorter (1 second) USB transfer timeout. However, the big one is a straight up hang of any TX endpoint until the NIC was reset. The RX side kept going just fine; only the TX endpoints would hang. Reproducing it was easy - just start up a couple of traffic streams on different WME AC's - eg a best effort + bulk transfer, like browsing the web and doing an ssh clone - throw in a ping -i 0.1 to your gateway, and it would very quickly hit device timeouts every couple of seconds. I put everything into a single TX EP and the hangs went away. Well, mostly. So after some MORE digging, I found that this driver isn't checking if the transfers are going into the correct EPs for the packet WME access category / 802.11 TID; and would frequently be able to schedule multiple transfers into the same endpoint. Then there's a second problem - there's an array of endpoints used for setting up the USB device, with .endpoint = UE_ADDR_ANY, however they're also being setup with the same endpoint configured in multiple transfer configs. Eg, a NIC with 3 or 4 bulk TX endpoints will configure the BK and BE endpoints with the same physical endpoint ID. This also leads to timed out transfers. My /guess/ was that the firmware isn't happy with one or both of the above, and so I solved both. * drop the USB transfer timeout to 1 second, not 5 seconds - that way we'll either get a 1 second traffic pause and USB transfer failure, or a 5 second device timeout. Having both the TX timeout and the USB transfer timeout made recovery from a USB transfer timeout (without a NIC reset) almost impossible. * enforce one transfer per endpoint; * separate pending/active buffer tracking per endpoint; * each endpoint now has its own TX callback to make sure the queue / end point ID is known; * and only frames from a given endpoint pending queue is going into the active queue and into that endpoint. * Finally, create a local wme2qid array and populate it with the endpoint mapping that ensures unique physical endpoint use. Locally tested: * rtl8812AU, 11n STA mode * rtl8192EU, 11n STA mode (with diffs to fix the channel config / power timeouts.) Differential Revision: https://reviews.freebsd.org/D47522
