I did some more testing, and even with the setting hw.ixl.enable_head_writeback
= 0 I still get to a situation where no packets are transmitted.

I don't have a test environment either.
But since ixl uses iflib on 12.x and 13.x, I expected this issue has gone away.

Hello Vincenzo!
This issue is present on FreeBSD 12.2 or 13.0? I don't have a test environment
right now, but I will upgrade a production router

What happens if you change /boot/loader.conf to set the default number of
queues to 8, and you never change that?
Same behaviour?

From the log it's quite clear that the problem is that netmap TXSYNC is

The compilation problems have been fixed.
