+ * Packets which match a rule in the classifier table chain
+ * will be traced. The tables are automatically ordered so that
+ * matches in the most specific table are tried first.
+ *
+ * It's reasonably likely that folks will configure a single
+ * table with one or two matches. As a result, we configure
+ * 8 hash buckets and 128K of match rule space. One can override
+ * the defaults by specifiying "buckets <nnn>" and "memory-size <xxx>"
+ * as desired.
+ *
+ * To build up complex filter chains, repeatedly issue the
+ * classify filter debug CLI command. Each command must specify the desired
+ * mask and match values. If a classifier table with a suitable mask
+ * already exists, the CLI command adds a match rule to the existing table.
+ * If not, the CLI command add a new table and the indicated mask rule
+ *
+ * Here is a terse description of the "mask <xxx>" syntax:
+ *
+ * l2 src dst proto tag1 tag2 ignore-tag1 ignore-tag2 cos1 cos2 dot1q dot1ad
+ *
+ * l3 ip4 <ip4-mask> ip6 <ip6-mask>
+ *
+ * <ip4-mask> version hdr_length src[/width] dst[/width]
+ * tos length fragment_id ttl protocol checksum
+ *
+ * <ip6-mask> version traffic-class flow-label src dst proto
+ * payload_length hop_limit protocol
+ *
+ * l4 tcp <tcp-mask> udp <udp_mask> src_port dst_port
+ *
+ * <tcp-mask> src dst # ports
+ *
+ * <udp-mask> src_port dst_port
+ *
+ * To construct matches, add the values to match after the indicated keywords:
+ * in the match syntax. For example:
+ * mask l3 ip4 src -> match l3 ip4 src 192.168.1.11
+ *
+ * @cliexpar
+ * Configuring the classify filter
+ *
+ * Configure a simple classify filter, and configure pcap rx trace to use it:
