Also, I understand there is no checksum offloading, is this being
worked on by someone? Is there a NetBSD maintainer for this code that
I could solicit some specific hints?

Checksum offloading is present... e.g.:

# ifconfig wm0
wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=2bf80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Tx,UDP6CSUM_Tx>

Okay, I'll look at those sources. Thanks.

The manpage (at the end) indicates that it is unimplemented
(and certainly doesn't seem to implement anything like FreeBSD did):

BUGS
     This driver is experimental.

     Support for checksum offload is unimplemented.

     Performance with at least some Marvell-based adapters is poor, especially
     on loaded PCI buses or when the adapters are behind PCI-PCI bridges.  It
     is believed that this is because the Marvell parts have significantly
     less buffering than the original SysKonnect cards had.
