From 4ffb17f5c3244e405198ae285ffbb20a62e0d4b3 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Fri, 5 Jun 2009 14:47:23 -0600 Subject: [PATCH] virtio-net: Increase filter and control limits Increase the size of the perfect filter table and control queue depth. This should give us more headroom in the MAC filter and is known to be needed by at least one guest user. Increasing the control queue depth allows a guest to feed several commands back to back if they so desire rather than using the send and wait approach Linux uses.
