Re: 6.9amd64 'dhcpd re0' won't listen/reply DHCP requests on Realtek 8168 RTL8168H/8111H
Hi list,
On re1 interface RTL8168H/8111H
re1: watchdog timeout
re1: watchdog timeout
re1: watchdog timeout
...
kernel messages appeared from time to time when re1 working in DHCP client mode.

Re: 6.9amd64 'dhcpd re0' won't listen/reply DHCP requests on Realtek 8168 RTL8168H/8111H
When I restarted by 'rcctl restart dhcpd' with flags from '/etc/rc.conf.local' 'dhcpd_flags="re0 re1"' client has got IP address from re0 - RTL8168EP/8111EP, but no address from re1 - RTL8168H/8111H interface. Looks like a bug somewhere.

Umm, start dhcpd using “dhcpd re0 re1”?

Re: 6.9amd64 'dhcpd re0' won't listen/reply DHCP requests on Realtek 8168 RTL8168H/8111H
Hi,
It seems a bug is still present in re(4) driver even in OpenBSD 6.9
RTL8168H/8111H adapter.
Freshly booted machine (address not assigned even during boot process) without
any cable disconnections or sleep/resume RTL8168H/8111H completely ignores DHCP
requests from any clients.
Don't know how to deal with it.

I can't reproduce this problem with the re0 RTL8168H/8111H in my AMD
B450 board. I guess that not every RTL8168H/8111H has problems; there
was an earlier bug report about RTL8168H/8111H at
https://marc.info/?l=openbsd-bugs=159403196706770=2
The rest of this mail only shows my dhcpd configuration, and might be
useless, because you have a working dhcpd on another interface.
I connected an Ethernet wire from "pehcehwahn" re0 to "maryland" gem0
and ran dhcpd re0. The wire was loose (ifconfig re0 said, "status:
no carrier"), but it began to work after I fixed the wire. The link
is 100baseTX because my gem(4) can't gigabit.--George

Small update: The laptop has two integrated adapters: re0 is: RTL8168EP/8111EP - dhcpd re0 -> dhcp server works and give IPs to clients; re1 is: RTL8168H/8111H - dhcpd re1 -> dhcpd server does not reply to client's requests.
