usbnet: smsc95xx: disable carrier check while suspending

2018-11-23T07:17:07+00:00

[ Upstream commit 7b900ead6cc66b2ee873cb042dfba169aa68b56c ]

We need to make sure, that the carrier check polling is disabled
while suspending. Otherwise we can end up with usbnet_read_cmd()
being issued when only usbnet_read_cmd_nopm() is allowed. If this
happens, read operations lock up.

net: smsc95xx: Fix MTU range

2018-11-23T07:17:06+00:00

[ Upstream commit 85b18b0237ce9986a81a1b9534b5e2ee116f5504 ]

The commit f77f0aee4da4 ("net: use core MTU range checking in USB NIC
drivers") introduce a common MTU handling for usbnet. But it's missing
the necessary changes for smsc95xx. So set the MTU range accordingly.

This patch has been tested on a Raspberry Pi 3.

smsc95xx: Check for Wake-on-LAN modes

2018-09-29T18:31:29+00:00

The driver does not check for Wake-on-LAN modes specified by an user,
but will conditionally set the device as wake-up enabled or not based on
that, which could be a very confusing user experience.
