[PATCH 5.10 114/122] bnxt_en: log firmware debug notifications

[Greg Kroah-Hartman]

From: Edwin Peer <edwin.peer@xxxxxxxxxxxx>

[ Upstream commit a44daa8fcbcf572545c4c1a7908b3fbb38388048 ]

Firmware is capable of generating asynchronous debug notifications.
The event data is opaque to the driver and is simply logged. Debug
notifications can be enabled by turning on hardware status messages
using the ethtool msglvl interface.
