This adds a driver for the CDC Ethernet part of this modem. The
device's ID is blacklisted in cdc_ether.c and is white-listed in
this new driver because of the quirks needed to make it useful.
The modem's firmware exposes a CDC ACM port for modem control and a
CDC Ethernet port for network data. The descriptors look fine but
both ports actually are some sort of multiplexers requiring non-
standard headers added/removed from every packet or they get
ignored. All information is based on a usb traffic log from a
Windows machine.
On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.
Userspace scripts are required to talk to the CDC ACM port.

When we register an rtc device at boot, we read the alarm value
in hardware and set the rtc device's aie_timer to that value.
The initial method to do this was to simply call rtc_set_alarm()
with the value read from hardware. However, this may cause problems
as rtc_set_alarm may enable interupts, and the RTC alarm might fire,
which can cause invalid pointer dereferencing since the RTC registration
is not complete.
This patch solves the issue by initializing the rtc_device.aie_timer
y hand via rtc_initialize_alarm(). This avoids any calls to the RTC
hardware which might enable interrupts too early.

carl9170 should set IEEE80211_TX_STAT_AMPDU_NO_BACK to generate a

This is needed for determining the reason for failure when a softdog
timeout occurs.
We use softdog to watch for critical application failures and at the
minimum a snapshot of the system would help to determine the cause. In
such a scenario the application could fail but there isn't a softlockup as
such, hence the detect softlockup feature does not help.
The patch adds a module parameter soft_panic which when set to 1 causes
softdog to invoke panic instead of reboot when the softdog timer expires.
By invoking panic we execute kdump if it is configured and the vmcore
generated by kdump should provide atleast a minimal idea of the reason for
failure.

It turns out we are only applying the interrupt coalescing settings

that queue we ran faster.
