Re: [PATCH net-next v2 00/11] bnxt_en: Implement new driver APIs to send FW messages

Hello:

This series was applied to netdev/net-next.git (refs/heads/master):

On Sun, 29 Aug 2021 03:34:55 -0400 you wrote:
The current driver APIs to send messages to the firmware allow only one
outstanding message in flight.  There is only one buffer for the firmware
response for each firmware channel.  To send a firmware message, all
callers must take a mutex and it is released after the firmware response
has been read.  This scheme does not allow multiple firmware messages
in flight.  Firmware may take a long time to respond to some messages
(e.g. NVRAM related ones) and this causes the mutex to be held for
a long time, blocking other callers.
