xdp_umem.c had overlapping changes between the 64-bit math fix for the calculation of npgs and the removal of the zerocopy memory type which got rid of the chunk_size_nohdr member. The mlx5 Kconfig conflict is a case where we just take the net-next copy of the Kconfig entry dependency as it takes on the ESWITCH dependency by one level of indirection which is what the 'net' conflicting change is trying to ensure.

2020-02-23net: usb: qmi_wwan: restore mtu min/max values after raw_ip switchDaniele Palmas1-0/+3
usbnet creates network interfaces with min_mtu = 0 and max_mtu = ETH_MAX_MTU. These values are not modified by qmi_wwan when the network interface is created initially, allowing, for example, to set mtu greater than 1500. When a raw_ip switch is done (raw_ip set to 'Y', then set to 'N') the mtu values for the network interface are set through ether_setup, with min_mtu = ETH_MIN_MTU and max_mtu = ETH_DATA_LEN, not allowing anymore to set mtu greater than 1500 (error: mtu greater than device maximum). The patch restores the original min/max mtu values set by usbnet after a raw_ip switch.

2020-02-10qmi_wwan: unconditionally reject 2 ep interfacesBjørn Mork1-27/+15
We have been using the fact that the QMI and DIAG functions usually are the only ones with class/subclass/protocol being ff/ff/ff on Quectel modems. This has allowed us to match the QMI function without knowing the exact interface number, which can vary depending on firmware configuration. The ability to silently reject the DIAG function, which is usually handled by the option driver, is important for this method to work. This is done based on the knowledge that it has exactly 2 bulk endpoints. QMI function control interfaces will have either 3 or 1 endpoint. This rule is universal so the quirk condition can be removed. The fixed layouts known from the Gobi1k and Gobi2k modems have been gradually replaced by more dynamic layouts, and many vendors now use configurable layouts without changing device IDs. Renaming the class/subclass/protocol matching macro makes it more obvious that this is now not Quectel specific anymore.

2020-02-10qmi_wwan: re-add DW5821e pre-production variantBjørn Mork1-0/+1
Commit f25e1392fdb5 removed the support for the pre-production variant of the Dell DW5821e to avoid probing another USB interface unnecessarily. However, the pre-production samples are found in the wild, and this lack of support is causing problems for users of such samples. It is therefore necessary to support both variants. Matching on both interfaces 0 and 1 is not expected to cause any problem with either variant, as only the QMI function will be probed successfully on either. Interface 1 will be rejected based on the HID class for the production variant: T: Bus=01 Lev=03 Prnt=04 Port=00 Cnt=01 Dev#= 16 Spd=480 MxCh= 0 D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 2 P: Vendor=413c ProdID=81d7 Rev=03.18 S: Manufacturer=DELL S: Product=DW5821e Snapdragon X20 LTE S: SerialNumber=0123456789ABCDEF C: #Ifs= 6 Cfg#= 1 Atr=a0 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.)

2019-04-08qmi_wwan: Add quirk for Quectel dynamic configKristian Evensen1-34/+31
Most, if not all, Quectel devices use dynamic interface numbers, and users are able to change the USB configuration at will. Matching on for example interface number is therefore not possible. Instead, the QMI device can be identified by looking at the interface class, subclass and protocol (all 0xff), as well as the number of endpoints. The reason we need to look at the number of endpoints, is that the diagnostic port interface has the same class, subclass and protocol as QMI. However, the diagnostic port only has two endpoints, while QMI has three. Until now, we have identified the QMI device by combining a match on class, subclass and protocol, with a call to the function quectel_diag_detect(). In quectel_diag_detect(), we check if the number of endpoints matches for known Quectel vendor/product ids. Adding new vendor/product ids to quectel_diag_detect() is not a good long-term solution. This commit replaces the function with a quirk, and applies the quirk to affected Quectel devices that I have been able to test the change with (EP06, EM12 and EC25). If the quirk is set and the number of endpoints equal two, we return from qmi_wwan_probe() with -ENODEV.

Quectel EG12 (module)/EM12 (M.2 card) is a Cat. 12 LTE modem. The modem behaves in the same way as the EP06, so the "set DTR"-quirk must be applied and the diagnostic-interface check performed.

Recent firmware revisions have added the ability to force these modems to USB2 mode, hiding their SuperSpeed capabilities from the host. The driver has been using the SuperSpeed capability, as shown by the bcdUSB field of the device descriptor, to detect the need to enable the DTR quirk. This method fails when the modems are forced to USB2 mode by the modem firmware. Fix by unconditionally enabling the DTR quirk for the affected device IDs.

2018-09-10qmi_wwan: Support dynamic config on Quectel EP06Kristian Evensen1-1/+29
Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB interfaces, without the device changing VID/PID or configuration number. When the configuration is updated and interfaces are added/removed, the interface numbers change. This means that the current code for matching EP06 does not work. This patch removes the current EP06 interface number match, and replaces it with a match on class, subclass and protocol. Unfortunately, matching on those three alone is not enough, as the diag interface exports the same values as QMI. The other serial interfaces + adb export different values and do not match. The diag interface only has two endpoints, while the QMI interface has three. I have therefore added a check for number of interfaces, and we ignore the interface if the number of endpoints equals two.

2018-05-28qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device IDBjørn Mork1-1/+1
SIMCOM are reusing a single device ID for many (all of their?) different modems, based on different chipsets and firmwares. Newer Qualcomm chipset generations require setting DTR to wake the QMI function. The SIM7600E modem is using such a chipset, making it fail to work with this driver despite the device ID match. Fix by unconditionally enabling the SET_DTR quirk for all SIMCOM modems using this specific device ID. This is similar to what we already have done for another case of device IDs recycled over multiple chipset generations: 14cf4a771b30 ("drivers: net: usb: qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201") Initial testing on an older SIM7100 modem shows no immediate side effects.
