Analyze and fix the following issue in the Linux kernel code: e1000: Do not truncate TSO TCP header with 82544 workaround
Problem Details: The e1000 driver has a workaround for 82544 on PCI-X where if the terminating byte of a buffer is at addresses 0-3 mod 8, then 4 bytes are shaved off it and defered to a new segment. This is due to an erratum that could otherwise cause TX hangs. Unfortunately this breaks TSO because it may cause the ...
