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.
