From: Ori Kam <or...@nvidia.com> Until now the number of pattern templates that was supported per table was limited to 2. This was the result of the limitation that the table could only support 1 matcher. which meant that we could only support merge of Ipv4 + TCP and IPv4 + UDP. With the added ability to use extended hash it is now possible to use more than 2 pattern templates in a single table. Extended match works by creating the hash of the rule based on the intersection of all pattern templates. As a result this is good for tables with small number of rules or that the intersection is very large. for example ACL table. Using this feature is not recommended to for use in tables with large number of rules or with small intersection. Using this feature on such cases may result in PPS degradation and rule insertion failures. This patch increase the max number to 32.
