Avoid spurious link status logs that may ultimately be wrong; for example, if the link is set to down with the cable plugged, then the cable is unplugged and after this the link is set to up, the last new log that is appearing is incorrectly telling that the link is up. In order to avoid errors, show link status logs after link_reset processing, and in order to avoid spurious as much as possible, only show the link loss when some link status change is detected. cc: stable@vger.kernel.org Fixes: e2ca90c276e1 ("ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver") Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> --- v3: - Add net as target tree in the subject. - Use constant string instead of variable because no other value is possible. v2: https://lore.kernel.org/netdev/20240618115054.101577-1-jtornosm@redhat.com/ - Fix the nits v1: https://lore.kernel.org/netdev/20240617103405.654567-1-jtornosm@redhat.com/ drivers/net/usb/ax88179_178a.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-)
