Subject: [PATCH] xen: flush queue when getting an event
|
||
|
|
|
||
|
|
xen does not have a register that, when written, will cause can_receive
|
||
|
|
to go from false to true. However, flushing the queue can be attempted
|
||
|
|
whenever the front-end raises its side of the Xen event channel. There
|
||
|
|
is a single event channel for tx and rx.
