Hello,
I'm having a problem connecting using RDMA_CM over ethernet. I have
two machines each with a Mellanox MT26428. The ethernet ports are
connected through an arista 10G switch. The IB ports are connected
through an IB switch.
The test programs rdma_lat or ucmatose run successfully over
This patch-series implements doorbell drop recovery for T4 iWARP driver.
In the event where DBs are dropped application can get stalled for one or more
reasons. So, we recover RDMA and LLD queues in such an event.
We also take care for handling DB overflow events.
The patch-series also has some

Hold the link state machine until the tuning data is read
from the QSFP EEPROM so correct tuning settings are applied
before the state machine attempts to bring the link up.
Link is also held on cable unplug in case a different cable is
used.
