[dpdk-dev] [PATCH] ethdev: increase flow type limit from 32 to 64

Kirill Rybalchenko kirill.rybalchenko at intel.com
Mon Nov 27 13:29:47 CET 2017


Increase the internal limit for flow types from 32 to 64
to support future flow type extensions.
Change type of variables from uint32_t[] to uint64_t[]:
  rte_eth_fdir_info.flow_types_mask
  rte_eth_hash_global_conf.sym_hash_enable_mask
  rte_eth_hash_global_conf.valid_bit_mask

This modification affects the following components:
  net/i40e
  net/enic
  net/mlx5
  net/ixgbe
  app/testpmd
