From 71a0ff65a21bf3e2c4fde208c4a635ed2bbb4e81 Mon Sep 17 00:00:00 2001 From: Majd Dibbiny Date: Thu, 21 Dec 2017 17:38:26 +0200 Subject: IB/mlx5: Fix congestion counters in LAG mode Congestion counters are counted and queried per physical function. When working in LAG mode, CNP packets can be sent or received on both of the functions, thus congestion counters should be aggregated from the two physical functions.
