I apologize for wasting your time. I went back to my system which uses a custom
kernel config and began testing. My configuration file includes RSS which is
not part of the GENERIC config:

options         PCBGROUP                # Distributed Protocol Control Block
Groups
options         RSS                     # Receive Side Scaling

When I commented out RSS and PCBGROUP (required for RSS) and rebuilt the
kernel, I had no trouble with ssh/nc TCP connections. However I use RSS across
multiple NICs and with it included in the kernel I see instability with TCP
(ssh inbound failing, wget outbound failing).
