====================
qed: Fix the Doorbell Overflow Recovery mechanism

This patch series fixes and improves the doorbell recovery mechanism.
The main goals of this series are to fix missing attentions from the
doorbells block (DORQ) or not handling them properly, and execute the
recovery from periodic handler instead of the attention handler.

Please consider applying the series to net.
