I have some other series [1,2] which have also received little-to-no feedback. Should
I resend those as well? I didn't ping about these earlier because there was a merge
window open, and e.g. gregkh has told me not to ping at that time (since series will
be reviewed afterwards). Should I be pinging sooner on netdev?

For netdev, you need to resend after the merge window. Other
subsystems might look at older patch, and if they apply cleanly might
merge them. But not netdev.
