From 01954fd3db492ef631e3e29bb70435fc3e68d1a8 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 14 May 2020 19:33:02 +0100 Subject: [PATCH] net: dsa: felix: fix incorrect clamp calculation for burst Currently burst is clamping on rate and not burst, the assignment of burst from the clamping discards the previous assignment of burst. This looks like a cut-n-paste error from the previous clamping calculation on ramp. Fix this by replacing ramp with burst.
