Dear colleagues,
experimenting with new amd64-based router we found strange re(4) behaviour when working in autoselect media mode:
whenever promisc mode turned on, renegotiating occurs, leading to 3 to 45 (depending on STP settings on the switch) network unavailability.
Moreover, some other re(4) setting changes seem to disturb link state unneededly (such as ifconfig re0 -vlanhwtag)
The most annoying fact is that we non-autonegotiating mode with our re and D-Link gigabit switches: fixing media at 1000BaseTX leads to link down regardless of master/slave settings on both sides; on re side it is even undocumented.
Any clues?
Thanks in advance.

Further investigation revealed even more weirdness of re driver:
If re card plugged into switch (tested with Catalyst 2948G) with fixed port speed/duplex (100/full) settings, and we trying to reboot - re driver fails to attach:
re0: <RealTek 8169S Single-chip Gigabit Ethernet> port 0xd000-0xd0ff mem 0xcfffbf00-0xcfffbfff irq 16 at device 11.0 on pci0 miibus0: <MII bus> on re0 rgephy0: <RTL8169S/8110S media interface> on miibus0 rgephy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 1000baseTX-FDX, auto re0: bpf attached re0: Ethernet address: 00:11:09:cd:15:77 re0: diagnostic failed, failed to receive packet in loopback mode re0: attach aborted due to hardware diag failure rgephy0: detached miibus0: detached device_attach: re0 attach returned 5
If switch port configured for 'auto' mode we can reboot without problems.
