Hello all,

Just for the record, I have a Broadcom NetLink Gigabit Ethernet NIC with
PCI IDs V14E4 (Broadcom, obviously), D1693.  My Windows XP driver is
b57xp32.sys.

I had encountered an issue where I could ping and perform any sort of
UDP to my hosted coLinux, but TCP wasn't working.  My coLinux' service
had parameters something like:

... ... ... (Solution omitted from previous e-mail)



Just reporting that I can reproduce the problem (and solution) on a
Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller (VENdor 11AB,
DEVice 4362), which is the wired NIC on some Apple MacBook computers.
For this NIC, the setting was called TCP/UDP Checksum Offload (IPv4) and
one can reproduce the issue with the On setting.

Have a nice day.
