Subject: [PATCH v3 net-next 11/13] qed: Debug feature: ilt and mdump
Part of the FW drop includes new debug capabilities implemented in the
qed_debug file. This patch dumps additional information during ethtool -d
for better debugging. The data dumped is the ilt (internal logical table)
and information gathered by the management firmware incase there was a
crash and driver was not able to extract the information (mdump).
