            Bug ID: 259665
           Summary: VNET/stability issues on ASIX AX88179 on USB
           Product: Base System
           Version: 12.2-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org

Hi, I come here from TrueNAS's bugtracker:
https://jira.ixsystems.com/browse/NAS-113168

After updating FreeNAS 11.3 (FreeBSD 11.x?) to TrueNAS 12.0 (FreeBSD
12.2-RELEASE-p10) i've begun to have issues with my network adapter. I've been
using a D-Link DUB-1312 which is a USB3 Ethernet adapter based on ASIX AX88179
chipset.

One issue is that my jails that are using VNET can't access most of the
internet - most HTTPS requests hang after connecting, some HTTP requests hang
when downloading data, jails themselves are accessible from LAN however. Jails
that aren't under VNET work fine.

Another issue is that sometimes network adapter would sometimes spontaneously
die, requiring a full reboot to recover, at least TrueNAS's command line says
"Restarting interfaces: failed" or something when I try to recover it.

I'm using this USB3 interface because on this setup it's either USB or onboard
realtek ethernet adapter which had massive stability issues on FreeNAS 11. I
can't use a PCIe NIC since the only slot on this MiniITX mobo is occupied by
SATA card.
