From e66cbc961cfe375f977b3bfae13abec4df8c8521 Mon Sep 17 00:00:00 2001 From: Paul Blakey Date: Tue, 26 Nov 2019 14:13:42 +0200 Subject: [PATCH] net/mlx5: ft: Use getter function to get ft chain FT chain is defined as the next chain after tc. To prepare for next patches that will increase the number of tc chains available at runtime, use a getter function to get this value. The define is still used in static fs_core allocation, to calculate the number of chains. This static allocation will be used if the relevant capabilities won't be available to support dynamic chains.
