You should try to go through the testst on ipxe.org/dev/driver to see if
your NIC passes all the tests. To me it seems like there might be an
issue without link detection. To me it seems like ifopen returns before
the interface is ready to receive traffic.

If you're using a Cisco switch I believe you need to enable portfast to
avoid the issue (if that is the issue and not something else). On other
switches I'm not sure what it's called.
