From 05f3d5bc23524bed6f043dfe6b44da687584f9fb Mon Sep 17 00:00:00 2001 From: Hariprasad Kelam Date: Thu, 17 Aug 2023 12:00:06 +0530 Subject: [PATCH] octeontx2-af: SDP: fix receive link config On SDP interfaces, frame oversize and undersize errors are observed as driver is not considering packet sizes of all subscribers of the link before updating the link config.
