This patch checks that MHI queue is not full before waking up the net queue. This fix sporadic MHI queueing issues in xmit. Indeed xmit and its symmetric complete callback (ul_callback) can run concurently, it is then not safe to unconditionnaly waking the queue in the callback without checking queue fullness. Fixes: 3ffec6a1 ("net: Add mhi-net driver") Signed-off-by:
