This looks okay. I see no interface errors, which is good.

msk(4) appears to be using MSI/MSI-X here.
One thing worth trying would be to disable MSI/MSI-X. You can disable
these by adding the following to your /boot/loader.conf :
hw.pci.enable_msix="0"
hw.pci.enable_msi="0"

Those errors at the end of your dmesg don't look good; could be the sign
of a NIC or motherboard that's going bad, or possibly a very strange
driver problem.
Adding Yong-Hyeon PYUN to this thread, since he helps maintain the
msk(4) driver. Yong-Hyeon, do you know of any conditions where heavy
network I/O could cause msk(4) to lock up or stop transmitting traffic,
or possibly hard-lock on ifconfig down/up?
