Fwd: Cinterion plugin patch

[matthew stanger]

Code looks awesome (*¬*), so much to learn for me. A few comments which are
all trivial and really don't need to be included but in attempt to be as
detailed as you

It's really stupid but the reason for this mapping is for the PLS-X only,
specifically when using Verizon Wireless as a carrier. As I interpret it
this would also mean Verizon wouldn't be able to support dual SIM
connections either. When I get to the dual SIM patch I'll be sure to keep
it in mind but for now it's just an FYI.

  /* Map PDP context from the current Bearer. USB0 -> 3rd context, USB1 ->
1st context.
     * In Verizon Wireless networks PDP contexts with APN class 1, 2 and 4
are dedicated to specific profile settings
     * for LTE (see AT^SGAPN), meaning that <cid> 1, 2 and 4 are not
allowed to be used for DUN, WWAN (RmNet)
     * or IP service connections. */

Just curious why we moved this back to the 1st step? I thought you didn't
want to create MBearerIpConfig before knowing if the modem is connected?
