qmi_wwan: fix interface number for DW5821e production firmware

2018-07-24T23:37:13+00:00

The original mapping for the DW5821e was done using a development
version of the firmware. Confirmed with the vendor that the final
USB layout ends up exposing the QMI control/data ports in USB
config #1, interface #0, not in interface #1 (which is now a HID
interface).

net: usb: asix: replace mii_nway_restart in resume path

2018-07-18T20:43:16+00:00

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

net: usb: rtl8150: demote allmulti message to dev_dbg()

2018-07-18T06:09:39+00:00

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().

net: lan78xx: Fix race in tx pending skb size calculation

2018-07-16T21:12:56+00:00

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.

This patch was tested on Raspberry Pi 3B+

qmi_wwan: add support for Quectel EG91

This adds the USB id of LTE modem Quectel EG91. It requires the
same quirk as other Quectel modems to make it work.

smsc75xx: Add workaround for gigabit link up hardware errata.

In certain conditions, the device may not be able to link in gigabit mode. This software workaround ensures that the device will not enter the failure state.

net: lan78xx: Use s/w csum check on VLANs without tag stripping

2018-06-26T13:53:29+00:00

Observations of VLANs dropping packets due to invalid
checksums when not offloading VLAN tag receive.
With VLAN tag stripping enabled no issue is observed.

net: lan78xx: Allow for VLAN headers in timeout calcs

2018-06-26T13:53:29+00:00

The frame abort timeout being set by lan78xx_set_rx_max_frame_length
didn't account for any VLAN headers, resulting in very low
throughput if used with tagged VLANs.

Use VLAN_ETH_HLEN instead of ETH_HLEN to correct for this.
