Build number in the file name still worries me. Last time I've asked 
about it the thread kind of died off so I will re-state it.

My concern is that if we will be getting firmware releases with the same 
major-minor but different build numbers, then embedding the build number 
into the driver prevents loading of a newer firmware unless the kernel 
is also updated.

I am not sure if that is what we want. Perhaps it is not expected at all 
that will happen in production so it is not a concern?

Or if it could happen, perhaps we should either push back on the scheme 
- drop the build number and bump the minor in all cases, or 
alternatively for our purposes drop the build number from the driver and 
have a symlinked scheme on disk?

Regards,

Tvrtko

Hi Tvrtko,
Sincere apologies for responding so late. According to my understanding, Jeff correct me if I am wrong, we are finalizing the firmware version number for every kernel version. So a certain kernel will have only one possible firware major-minor and build number for a certain platform.

 I have cc-ed Jeff in this thread so he can add his comment on build number. Jeff, any comments?

Regards,
Anusha
