From bbdfebb08ff5eb67ae65539c8cbb728c8f246552 Mon Sep 17 00:00:00 2001 From: Maher Sanalla Date: Sun, 22 Jan 2023 21:09:40 +0200 Subject: net/mlx5: Store page counters in a single array [ Upstream commit c3bdbaea654d8df39112de33037106134a520dc7 ] Currently, an independent page counter is used for tracking memory usage for each function type such as VF, PF and host PF (DPU). For better code-readibilty, use a single array that stores the number of allocated memory pages for each function type.
