Could you test the following patch?
1) Add extra delay for BCM570[0-4]. This is not documented but
Linux tg3 does.
2) Insert a completion barrier at the end of bge_blockinit()
Unfortunately, that doesn't make things work - the same symptoms as before -
packets are transmitted with the correct mac address, but none are received
by the driver.
I added another fix into -current.

src/sys/dev/pci: if_bge.c if_bgereg.h
Add 40bit DMA bug workaround(BGEF_40BIT_BUG) from FreeBSD (part of r199670).
This workaround is for 5714/5715 controllers and is not actually a MAC
controller bug but an issue with the embedded PCIe to PCI-X bridge in the
This change uses bus_dmatag_subregion(), so this workaround won't work on some
archs which doesn't support bus_dmatag_subregion().
To generate a diff of this commit:
cvs rdiff -u -r1.261 -r1.262 src/sys/dev/pci/if_bge.c
cvs rdiff -u -r1.85 -r1.86 src/sys/dev/pci/if_bgereg.h
Ultra 45 has BCM5715. I don't know if this bug is related
to the problems we have.
For sparc64, bus_dmatag_subregion() is not supported yet,
so this change won't fix any problem.
