From 6cdc686aa3163192ebce8ea72efee806729172c2 Mon Sep 17 00:00:00 2001 From: Ariel Levkovich Date: Wed, 2 Dec 2020 21:46:04 +0200 Subject: [PATCH] net/mlx5: Increase hairpin buffer size The max packet size a hairpin queue is able to handle is determined by the total hairpin buffer size divided by 4. Currently the buffer size is set to 32KB which makes the max packet size to be 8KB and doesn't support jumbo frames of size 9KB. This change increases the buffer size to 64KB to increase the max frame size and support 9KB frames.
