c921560563 Turn TCP and UDP hardware RX checksumming back on. jlemon pointed out where 
I'd gone wrong before: we have to set csum_data to 0xffff, not 0.

1c352ef74a Use LGE_INC() macro to increment tx producer index in lge_encap(). 
Disable the extra TCP/UCP checksum checking in lge_rxeof() since it
doesn't appear to actually work as advertised.

6048cd628a In lge_detach(), don't contigfree() the jumbogram buffer memory; 
lge_free_jumbo_mem() does it for us.

c678bc4f13 Add device driver support for the Level 1 LXT1001 NetCellerator 
gigabit ethernet controller chip. This device is used on some
fiber optic gigE cards from SMC, D-Link and Addtron. Jumbograms and
TCP/IP checksum offload on receive are supported. Hardware VLAN
filtering is not, because it doesn't play well with our existing
VLAN code. Also add manual page.

There is a 4.x version of this driver available at
http://www.freebsd.org/~wpaul/Level1/4.x if anyone feels adventurous
and wants to test it. I still need to do performance testing and
tuning with this device.

(For my next trick, I will make the 3Com 3cR990 sit up and beg.)
