net: lan78xx: fix rx handling before first packet is send

2018-07-28T21:29:49+00:00

As long the bh tasklet isn't scheduled once, no packet from the rx path
will be handled. Since the tx path also schedule the same tasklet
this situation only persits until the first packet transmission.
So fix this issue by scheduling the tasklet after link reset.

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+
