Re: Appears rtw88 driver hangs network stack.

I discovered this during testing freebsd 14.1.

System description:

slimline is an HP Slimline Desktop - 290-p0014

Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz
Coffee Lake (Core i7)
Ethernet    RTL8111/8168/8411 and RTL8125 2.5GbE
Wi-Fi RTL8821CE

In an effort to reproduce, I pulled /usr/src and /usr/ports using git.

I started a buildworld and ssh'ed in and tail -f /var/log/Phase1.log.

After a short while, system is frozen to ssh, and can't use console 
either.  The latest changes were to network code, so I'll reboot and 
build and install world and kernel before I continue testing...

Here's my ifconfig before the lockup:
