Here is a bugfix for the Lance chip driver for the DECstation 2100/3100.
The fix is specific to the original DECstations (not the 5000's) and results
in persistent TCP checksum errors when a TCP connection's window size
adjusts such that the start offset is on a byte boundary. The problem
is that "from" is a signed char and sign extended over the high order
bits of the short.
