Although the type I ERSPAN is based on the barebones IP + GRE encapsulation and no extra ERSPAN header. Report erspan version on GRE interface looks unreasonable. Fix this by separating the erspan and gre fill info. IPv6 GRE does not have this info as IPv6 only supports erspan version 1 and 2. Reported-by:

After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be cleared, and another CPU can start napi thread and access per-CQ variable, cq->work_done. If the other thread (for example, from busy_poll) sets it to a value >= budget, this thread will continue to run when it should stop, and cause memory corruption and panic. To fix this issue, save the per-CQ work_done variable in a local variable before napi_complete_done(), so it won't be corrupted by a possible concurrent thread after napi_complete_done(). Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done variable race is fixed, so the driver is able to reliably support features like busy_poll.

On kernel 6.1-rcX, I have been getting the following dmesg error message on every boot, resume from suspend and rfkill unblock of the Bluetooth device: Bluetooth: hci0: HCI_REQ-0xfcf0 After some investigation, it turned out to be caused by commit dd50a864 ("Bluetooth: Delete unreferenced hci_request code") which modified hci_req_add() in net/bluetooth/hci_request.c to always print an error message when it is executed. In my case, the function was executed by msft_set_filter_enable() in net/bluetooth/msft.c, which provides support for Microsoft vendor opcodes. As explained by Brian Gix, "the error gets logged because it is using a deprecated (but still working) mechanism to issue HCI opcodes" [1]. So this is just a debugging tool to show that a deprecated function is executed. As such, it should not be included in the mainline kernel. See for example commit 771c0353 ("deprecate the '__deprecated' attribute warnings entirely and for good") Additionally, this error message is cryptic and the user is not able to do anything about it.

The rationale of showing this is that it's potentially critical information to diagnose and find more CSR compatibility bugs in the future and it will save a lot of headaches. Given that clones come from a wide array of vendors (some are actually Barrot, some are something else) and these numbers are what let us find differences between actual and fake ones, it will be immensely helpful to scour the Internet looking for this pattern and building an actual database to find correlations and improve the checks.

A patch series by a Qualcomm engineer essentially removed my quirk/workaround because they thought it was unnecessary. It wasn't, and it broke everything again: https://patchwork.kernel.org/project/netdevbpf/list/?series=661703&archive=both&state=* He argues that the quirk is not necessary because the code should check if the dongle says if it's supported or not. The problem is that for these Chinese CSR clones they say that it would work: = New Index: 00:00:00:00:00:00 (Primary,USB,hci0) = Open Index: 00:00:00:00:00:00 < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > HCI Event: Command Complete (0x0e) plen 12 > [hci0] 11.276039 Read Local Version Information (0x04|0x0001) ncmd 1 Status: Success (0x00) HCI version: Bluetooth 5.0 (0x09) - Revision 2064 (0x0810) LMP version: Bluetooth 5.0 (0x09) - Subversion 8978 (0x2312) Manufacturer: Cambridge Silicon Radio (10) ... < HCI Command: Read Local Supported Features (0x04|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 68 > [hci0] 11.668030 Read Local Supported Commands (0x04|0x0002) ncmd 1 Status: Success (0x00) Commands: 163 entries ...

Commit dacce2be ("vmxnet3: add geneve and vxlan tunnel offload support") added support for encapsulation offload. However, the pathc did not report correctly the encapsulated packet which is LRO'ed by the hypervisor. This patch fixes this issue by using correct callback for the LRO'ed encapsulated packet.
