This is an RFC patch that we sent to linux-wireless mailing list a while ago,
and it spawned a discussion regarding whether GPL sources has to be submitted
together with this firmware. We would like to clarify with linux-firmware maintainers
to understnad what should be our actions to allow this to be accepted.
- firmware contains GPL components;
- LICENCE file states that sources for GPL components will be provided on request
to oslegal@xxxxxxxxxxxxx

There was an opinion that it is not enough: precedent case like this with carl9170
firmware was resolved by submitting GPL sources into linux-firmware repository
itself.
Does the same applies to qsr10g firmware?
The SDK that we use to build it is quite heavy (> 100MB, but with toolchain). 
Maybe we can take another approach to place SDK separately on Quantenna website
(as a compressed archive), and add a link in linux-firmware?
