From 6ed68da870c391d88575dc027a3de4826a77f57e Mon Sep 17 00:00:00 2001 From: Nathan Hjelm Date: Thu, 11 Oct 2018 10:40:08 -0600 Subject: [PATCH] btl/uct: use the correct tl interface attributes It is apparently possible for different instances of the same UCT transport to have different limits (max short put for example). To account for this we need to store the attributes per TL context not per TL. This commit fixes the issue.
