We filter the E362 because it's managed by the Novatel LTE plugin. If we also
filter out the USB551L, but it's not explicitly grabbed by any other plugin, it
will default to the Generic one.
CDMA-only devices don't support +ZPAS for access tech loading, so chain up to the
parent so we get the QCDM fallback access tech loading functions.

During init, the N900 appears to ignore an E0 in the same command as
an E1. So just add another init command to disable echo, which won't
have any effect on devices that work with the first command.
This patch removes an unnecessary check of unsigned expression >= 0,
which also fixes the following clang warnings:
sierra/mm-broadband-modem-sierra.c:570:18: error: comparison of
unsigned expression >= 0 is always true
[-Werror,-Wtautological-compare]
mode >= 0 &&

Bug reported on https://code.google.com/p/chromium/issues/detail?id=235989
Patched by Yunlian Jiang <yunlian@chromium.org>
The GetNetworkTime() response is defined to be an ISO8601 string, which
is in turn defined to be in local time. Make sure that's reflected in
the documentation, and append the timezone offset to UTC where we have
it.
Oddly, Icera devices return their time info in UTC with an offset to
the local timezone, so we have to jump through some hoops there to
convert the response to localtime based on the reported offset.
Some additional fixes by Aleksander Morgado <aleksander@lanedo.com>.

Icera devices include bands that the modem doesn't support in
the %IPBM=? list, so the plugin sets the band to its current
enabled/disabled value to test whether that band is supported.
There were two problems with this approach:
1) Setting an already-enabled band to be enabled apparently
isn't a NOP; it might take more than the 3 seconds given, and
if the response comes after 3 seconds, this greatly confuses
ModemManager because the AT command/reply sequence is now
messed up. So increase the timeout to 10 seconds.
2) Why bother checking bands that are already enabled anyway?
We already know they are supported, so just don't check those
bands at all. This requires some parkour because we use the
parsed band array from %IPBM=? to track whether bands are
enabled/disabled by indexing into the array, so instead just
use two separate arrays. This actually makes the fix for #1
un-needed (because we never enable any bands) but it's good
to have #1 anyway.
The USB305 (Icera-based) apparently has a port that replies to everything
with ERROR, and that port is unusable. Make sure it's ignored, otherwise
MM may claim it as the primary AT port since it technically speaks AT.
WMC ports will return "ERROR" to all AT commands, except for "AT" itself. So
just provide a custom AT probing logic, which uses "ATE0" instead, and assumes
the port is not an AT port if an error is returned.
NM attempts to set allowed and preferred mode during the connection
process. The plugin x220x does not handle properly when NM request
allowed mode to '2g, 3g' and the preferred mode to 'none'.
This commit attempts to solve the problem described above. When this
situation happens, establish the mode of the modem has 'ANY' (which
seems the safest one) instead of just throwing an error.
