From 5a7e09d58f3fe2f0d5e8f0da4b1f686491245eb5 Mon Sep 17 00:00:00 2001 From: Guvenc Gulce Date: Tue, 1 Dec 2020 20:20:46 +0100 Subject: net/smc: Introduce SMCR get link command Introduce get link command which loops through all available links of all available link groups. It uses the SMC-R linkgroup list as entry point, not the socket list, which makes linkgroup diagnosis possible, in case linkgroup does not contain active connections anymore.
