Ok, that would indicate there is an interrupt delivery issue if all
others changes(including Marius' patch) are correct. Because there
is no publicly available data sheet for BCM57765 yet I'm not sure
what is real difference between BCM5717 and BCM57765. However I
guess they require similar hardware configuration. Both BCM5717 and
BCM57765 will use tagged status feature of controller if MSI is
available. And NVIDIA bridge controller is known to have MSI issues
for a long time in FreeBSD. Please check whether you received any
interrupts for bge(4) with vmstat(8). If you see no interrupt from
the output, either try disabling MSI or apply r219737 and r219740
and see whether that makes any difference.
