Hi David,

What I read: NXP (who has taken over the Marvell BLE/Wi-Fi business) is 
not willing to maintain products once they have sold it.

mwifiex does not continue to do anything on its own, it requires 
continuous maintenance. And NXP is not doing that:

$ git log --no-merges --oneline drivers/net/wireless/marvell/mwifiex/ | 
wc -l
643
$ git log --no-merges drivers/net/wireless/marvell/mwifiex/ | grep 
^Author:.*nxp.com | wc -l
7

What I read: NXP is eager to support new hardware, but does not take 
adequate support of hardware they sold in the past.

 From my PoV as a potential customer: NXP cleaning up the mwifiex driver 
would give me confidence that whatever comes next from NXP will be taken 
care of adequately too. Also in the long term, which is a must when 
choosing components for products that need to be supported for many 
years to come.

Kind regards,
