From: Mickey Spiegel <emspi...@us.ibm.com>
This patch adds a second logical switch ingress ACL stage, and
correspondingly a second logical switch egress ACL stage. This
allows for more than one ACL-based feature to be applied in the
ingress and egress logical switch pipelines. The features
driving the different ACL stages may be configured by different
users, for example an application deployer managing security
groups and a network or security admin configuring network ACLs
or firewall rules.
Each ACL stage is self contained. The "action" for the
highest-"priority" matching row in an ACL stage determines a
packet's treatment. A separate "action" will be determined in
each ACL stage, according to the ACL rules configured for that
ACL stage. The "priority" values are only relevant within the
context of an ACL stage.
ACL rules that do not specify an ACL stage are applied to the
default "acl" stage.
