This way a PMD/HW > can prepare all the resources needed for efficient flow rules creation in > the datapath. To avoid any hiccups due to memory reallocation, the maximum > number of flow rules is defined at the table creation time. > > The flow rule creation is done by selecting a table, a pattern template > and an actions template (which are bound to the table), and setting unique > values for the items and actions. > > Signed-off-by: Alexander Kozyrev <akozy...@nvidia.com> > ---
