From: Vivek Kumar Bhagat <redacted> Date: Thu, 11 Jun 2015 07:23:46 -0700 Subject: [PATCH] ax88179_178a: add reset functionality in reset_resume Without reset functionality in reset_resume, iperf connection does not establish after suspend/resume however ping works at the same time. iperf connection fails with wrong checksum error shown by tcpdump. reset function inside reset_resume solves above bug. We have verified this issue on ASIX based ST Lab, Cadyce dongle.
