okay, that's maybe not correct I want to drop the channel setting
feature while xmit which "could" be use for channel hoping On
multiple interfaces.

The reason are more... this is a sync callback and I can't deal with a
async xmit with that. Okay I can solve this to make the channel setting
async but... if somebody want channel hoping then the logic for that
should be in userspace. We don't have any kernelspace implementation of
any protocol which use the channel hoping feature.

btw. the wireless implementation forbids multiple interface with
different channels. [0]

[0] is a neat introduction how wireless userspace access works. Page
21/35 "only matching PHY parameters possible e.g. all virtual interfaces
are on one channel".
