Hi,
I have installed FreeBSD 14.0-CURRENT #1

on my notebook HP EliteBook 830 G7 and I am using RealTek usb LAN
interface:

When there is bigger load on the interface, for example rsync of the
big
directory, the carrier is lost. The only solution I found is to remove
and insert the usb interface; ifconfig ue0 down, ifconfig ue0 up did
not
help. The output of the ifconfig:
ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
options=68009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>

I do not know and did not find anything relevant, if the driver is
buggy
or the hardware has some problems. Please, advice.
I found that issuing a usbconf reset usually helps to bring it back.
That said I have a machine with a port on a root hub directly and there
it behaves a lot better compared to when I connect it to different port
on the 2nd root hub with an intermediate uhub on the same machine.
