Subject: phylink: ensure we report link down when LOS asserted
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5837f963300b63264dd1baf32e96063e807ca28c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

phylink: ensure we report link down when LOS asserted


[ Upstream commit ac817f5ad066697e4d4d35ec68c974eba2c5f17a ]

Although we disable the netdev carrier, we fail to report in the kernel
log that the link went down.  Fix this.
