Is there any hope of avoiding

May 22 15:16:14 node11 kernel: bge0: watchdog timeout -- resetting
May 22 15:16:14 node11 kernel: bge0: link state changed to DOWN
May 22 15:16:17 node11 kernel: bge0: link state changed to UP

/boot/loader.conf contains

I get the similar messages whether I have link0 or not and whether
I allow bge0 to autoselect media or force 1000baseTX <full-duplex>.

bge0 is connected to a SMC TigerSwitch SMC8624T.
