If anyone has any objections, please let me know. ------------------ From: Hariprasad Kelam [ Upstream commit 05f3d5bc23524bed6f043dfe6b44da687584f9fb ] 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. This patch fixes the same.
