From 42716425ad7e1b6529ec61c260c11176841f4b5f Mon Sep 17 00:00:00 2001 From: Sanjay R Mehta Date: Tue, 3 Aug 2021 07:34:56 -0500 Subject: [PATCH] thunderbolt: Fix port linking by checking all adapters In tb_switch_default_link_ports(), while linking of ports, only odd-numbered ports (1,3,5..) are considered and even-numbered ports are not considered. AMD host router has lane adapters at 2 and 3 and link ports at adapter 2 is not considered due to which lane bonding gets disabled. Hence added a fix such that all ports are considered during linking of ports.
