Firmware crash is a pretty rare event and can't happen too frequently as
|
||
|
|
it has to be followed by a hardware reinitialization and config reload.
|
||
|
|
It should be safe to don't use net_ratelimit() when it happens.
|
||
|
|
|
||
|
|
For reporting & debugging purposes it's important to provide a complete
|
||
|
|
log as the last lines are actually the most important. This change
|
||
|
|
modifies brcmfmac to print all messages in an unlimited way in that
|
||
|
|
specific case. With this change there should be finally a backtrace of
|
||
|
|
firmware finally visible after a crash.
