Hello Tomas,

Our real intention was to replace pci_enable_msix() with 
pci_enable_msix_range().
In V4, I had min as 8 and max as msi_count (which could be max of 32).  So 
range was 8 - 32.  But then as you suggested to make separate patch if I wanted 
to set the min range different, I have created patch 11 in V5.
In patch 10 of V5, set range as (1 - 32). - I thought this would reflect our 
original intention.
After discussed internally, we wanted to have at least minimum of 2 MSIx, so it 
reflects in patch 11 of V5.

Please let me know if you still think I missed something.

Thanks,

I don't this is correct, your original code hasn't allowed a single msi-x line 
too, it allowed it in an exact same range <2,8> like it is now with 10+11/11 
patch applied.
It looks like you have decided to not change the minimal supported value in the 
end, that means that not two but a single patch is preferred. If you for any 
reason repost your series, please merge
10+11 into a single patch.
I can accept it in the current form too so -
