Indeed, there was a lot of resistence to this due to the overhead
for small retransmit queue sizes, but with today's scale this is
long overdue.
So, series applied, nice work!
Maybe we can look into dynamic schemes where when the queue never
goes over N entries we elide the rbtree and use a list. I'm not
so sure how practical that would be.
Thanks!
