(Apologies, trying one more time with a better mailer)
Sorry it took so long, but I finally got a chance to test the patches. They
seem to work well, but they only get rid of the downlink / uplink speed spam -
I still get the following filling my kernel log with a patched kernel:
[ 29.830383] cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected
[ 29.894359] cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected
[ 29.958601] cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected
[ 30.022473] cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected
[ 30.086548] cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected
with the below patch on top of your 3, then my kernel log is clean.
Please apply your patches plus my patch, and feel free to add

to the other three.

Subject: [PATCH] CDC-NCM: remove "connected" log message
The cdc_ncm driver passes network connection notifications up to
usbnet_link_change(), which is the right place for any logging.
Remove the netdev_info() duplicating this from the driver itself.
This stops devices such as my "TRENDnet USB 10/100/1G/2.5G LAN"
(ID 20f4:e02b) adapter from spamming the kernel log with
cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected
messages every 60 msec or so.
