[PATCH 4.19 247/321] net: hns3: fix an issue for hns3_update_new_int_gl

From: Greg Kroah-Hartman
Date: Tue Dec 03 2019 - 18:01:44 EST


From: Peng Li <lipeng321@xxxxxxxxxx>

[ Upstream commit 6241e71e7207102ffc733991f7a00f74098d7da0 ]

HNS3 supports setting rx-usecs|tx-usecs as 0, but it will not
update dynamically when adaptive-tx or adaptive-rx is enable.
This patch removes the Redundant check.
