[dpdk-dev] [PATCH 23/52] i40e/base: Update Flex-10 related device/function capabilities

Sun Sep 6 09:11:37 CEST 2015


The Flex10 device/function capability has been upgraded to revision 2
to include information needed to support Flex-10 DCC and DCI
configurations. This patch adds new fields to the i40e_hw_capabilities
structure and updates i40e_parse_discover_capabilities functions to
extract them from the AQ response. Naming convention has changed to use
flex10 mode instead of existing mfp_mode_1.
