rG28df957acb93: if_cdce: Add support for setting RX filtering
rGf0c393f781f0: if_cdce: Add support for setting RX filtering

Summary

We can now set promisc and allmulti modes.
Filtering of given multicast addresses is not supported.
Changing the mode is done by sending a command described in:
"USB CDC Subclass Specification for Ethernet Devices v1.2, section 6.2.4".
This means that at least in theory this feature should work with all
modems that are using this driver.

This fixes Huawei E3372h-320 running new firmware in "HiLink" mode.
Previously it would reset a few seconds after its mode was changed with "usb_modeswitch".
Setting RX filter to default value at the end of attach function fixed that.
