From 37cd0a007f88f1d6269035bdb02b50f536cca8de Mon Sep 17 00:00:00 2001 From: "Klaus D. Wacker" Date: Wed, 22 Aug 2007 13:51:39 +0200 Subject: [PATCH] [S390] qdio: Refresh buffer states for IQDIO Asynchronous output queue Hipersocket Multicast queue works asynchronously. When sending buffers, the buffer state change may happen delayed. The tasklet for checking changes in the outbound queue excluded IQDIO async queues from this process. This created either a hang situation when the queue ran full, or presented a hang situation a interface close time. The tasklet processing is changed to include IQDIO async queues when requesting buffer state refresh. Signed-off-by: Klaus D.
