Hi Suresh,
I think it would be more normal to cite this commit something like this:
The limit of 64 was removed by
commit e56afa599609 ("i40e: Remove limit of 64 max queues per channel")
Also, it's not clear to me if this should be considered a fix or not.
If not, which I lean towards, then it should probably be targeted
at iwl-next.
Subject: [PATCH iwl-next] ...
If it is a fix, then it should have a Fixes tag and probably
be targeted at iwl.
Subject: [PATCH iwl] ...
...
