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.
