Subject: hv_netvsc: Fix the list processing for network change event
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=15cfd40771e18a4e9b788c64c9db2606f958b93d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

hv_netvsc: Fix the list processing for network change event

RNDIS_STATUS_NETWORK_CHANGE event is handled as two "half events" --
media disconnect & connect. The second half should be added to the list
head, not to the tail. So all events are processed in normal order.
