Public bug reported:
SRU Justification:
[Impact]
mlxbf_tmfifo driver does not always schedule work for VIRTIO CONSOLE
nottification. The result is with rshim console, the dmesg output would
be cut off or simply cat a big text file to stdout.
[Fix]
* Make sure TM_TX_LWM_IRQ bit is set when there is a notification of
virtio console event.
[Test Case]
* Compare the output of dmesg from rshim console and ssh session. Make sure
both are the same.
* Issue is reproduced w/o fix and compare the same dmesg output from the same
as above.
[Regression Potential]
The changes affect only virtio console event handling only and been
tested fully.
[Others]
This issue is the same on focal and Jammy.
