Add separate software Tx queue limit for non-TCP traffic to make total
limit higher and avoid local drops of TCP packets because of no
backpressure.
There is no point to make non-TCP limit high since without backpressure
UDP stream easily overflows any sensible limit.
Split early drops statistics since it is better to have separate counter
for each drop reason to make it unabmiguous.
Add software Tx queue high watermark. The information is very useful to
understand how big queues grow under traffic load.

Use standard mdoc macros instead of pure roff, fix some other mdoc usage,
make the style consistent, and fix some grammar issues.
