Subject: [PATCH] net: hns3: fix tm port shapping of fibre port is incorrect
after driver initialization
[ Upstream commit 12a3670887725df364cc3e030cf3bede6f13b364 ]
Currently in driver initialization process, driver will set shapping
parameters of tm port to default speed read from firmware. However, the
speed of SFP module may not be default speed, so shapping parameters of
tm port may be incorrect.
To fix this problem, driver sets new shapping parameters for tm port
after getting exact speed of SFP module in this case.
Fixes: 88d10bd6f730 ("net: hns3: add support for multiple media type")
