* | usbnet: smsc95xx: check for csum being in last four bytesBen Dooks2018-11-171-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | The manual states that the checksum cannot lie in the last DWORD of the transmission, so add a basic check for this and fall back to software checksumming the packet. This only seems to trigger for ACK packets with no options or data to return to the other end, and the use of the tx-alignment option makes it more likely to happen.

* | usbnet: smsc95xx: simplify tx_fixup codeBen Dooks2018-11-171-15/+13Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The smsc95xx_tx_fixup is doing multiple calls to skb_push() to put an 8-byte command header onto the packet. It would be easier to do one skb_push() and then copy the data in once the push is done. We also make the code smaller by using proper unaligned puts for the header. This merges in the CPU to LE32 conversion as well and makes the whole sequence easier to understand hopefully. Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: David S.

* | usbnet: smsc95xx: fix rx packet alignmentBen Dooks2018-11-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The smsc95xx driver already takes into account the NET_IP_ALIGN parameter when setting up the receive packet data, which means we do not need to worry about aligning the packets in the usbnet driver. Adding the EVENT_NO_IP_ALIGN means that the IPv4 header is now passed to the ip_rcv() routine with the start on an aligned address. Tested on Raspberry Pi B3.

* | net: ethernet: Convert phydev advertize and supported from u32 to link modeAndrew Lunn2018-11-111-11/+16
|/ | | | | | | | | | | | There are a few MAC/PHYs combinations which now support > 1Gbps. These may need to make use of link modes with bits > 31. Thus their supported PHY features or advertised features cannot be implemented using the current bitmap in a u32. Convert to using a linkmode bitmap, which can support all the currently devices link modes, and is future proof as more modes are added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * qmi_wwan: Support dynamic config on Quectel EP06Kristian Evensen2018-09-101-1/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mii_nway_restart is not pm aware which results in a rtnl deadlock. Implement mii_nway_restart manual by setting BMCR_ANRESTART if BMCR_ANENABLE is set. To reproduce: * plug an asix based usb network interface * wait until the device enters PM (~5 sec) * `ip link set eth1 up` will never return Fixes: d9fe64e51114 ("net: asix: Add in_pm parameter") Signed-off-by: Alexander Couzens <lynxis@fe80.eu> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver can spam the kernel log with multiple messages of: net eth0: eth0: allmulti set Usually 4 or 8 at a time (probably because of using ConnMan). This message doesn't seem useful, so let's demote it from dev_info() to dev_dbg(). Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * net: lan78xx: Fix race in tx pending skb size calculationStefan Wahren2018-07-161-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The skb size calculation in lan78xx_tx_bh is in race with the start_xmit, which could lead to rare kernel oopses. So protect the whole skb walk with a spin lock. As a benefit we can unlink the skb directly.
