Not sure but I'm probably not looking in the right places:

macropus% pwd
/usr/home/src/sys/pci
macropus% grep TXCSUM *
if_xl.c:#define XL905B_TXCSUM_BROKEN    1
if_xl.c:#ifdef XL905B_TXCSUM_BROKEN
if_xl.c:#ifdef XL905B_TXCSUM_BROKEN
if_xl.c:#ifndef XL905B_TXCSUM_BROKEN
if_xl.c:                if (ifp->if_capenable & IFCAP_TXCSUM)

macropus% sysctl -a | grep -i checksum
net.inet.udp.checksum: 1

Is there anywhere else I can look?

On the question of sk missing lower speeds, small correction -
ifconfig -m sk0 is correct and shows full set, it is the man page that
only mentions  GigE speeds.
