Great.

I am seeing this with the Zynq without the cadence_gem patch. I am
seeing IP header check sum errors. I suggest you check the stats for the
receiving end of your ping. My trace is:

# tcpdump -i bridge0 -vvvv ip host 10.10.5.15




tcpdump: listening on bridge0, link-type EN10MB (Ethernet), capture size
65535 bytes

Yeap.

I do not see this. That period is weird. I wonder is this is something
in the PHY when attempting to create a link. Also could it be in the
host side related to opening the tap interface and maybe a DNS type issue.
