[LEDE-DEV] [LEDE-DEV, 3/3, v3] uqmi: Prevent 'POLICY MISMATCH' error.

[Nikolay Ledovskikh]

I'm using multiple modems

config interface 'wan1'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option apn 'internet.megafon.ru'
        option ipv6 '0'
        option metric '1'

config interface 'wan2'
        option proto 'qmi'
        option device '/dev/cdc-wdm1'
        option apn 'internet.beeline.ru'
        option ipv6 '0'
        option metric '2'

And 2 more modems

And with your patch logread shows endlessly:

About cgdcont:
1'st modem:
at+cgdcont?
+CGDCONT: 1,"IP","internet.megafon.ru","0.0.0.0",0,0
+CGDCONT: 3,"IP","internet.megafon.ru","0.0.0.0",0,0

2'nd modem:
at+cgdcont?
+CGDCONT: 1,"IP","internet.beeline.ru","0.0.0.0",0,0
+CGDCONT: 3,"IP","internet.beeline.ru","0.0.0.0",0,0

And 2 more modems

Only one (wan2) gets up and connected to network. What I'm doing wrong?
