Hi,

After a timeout event caused by for example a broadcast storm, when
the MAC and PHY are reset, the BQL TX queue needs to be reset as
well. Otherwise, the device will exhibit severe performance issues
even after the storm has ended.
What are the symptomns ?
Is this reset needed on any network driver in that case, or is it
something particular for the ucc_geth ?
For instance, the freescale fs_enet doesn't have that reset. Should it
have it too ?
