r8169: TSO fixes.
- the MSS value is actually contained in a 11 bits wide (0x7ff) field.
The extra bit in the former MSSMask did encompass the TSO command
bit ("LargeSend") as well (0xfff). Oops.
- the Tx descriptor layout is not the same through the whole chipset
family. The 8169 documentation, the 8168c documentation and Realtek's
drivers (8.020.00, 1.019.00, 6.014.00) highlight two layouts:
1. 8169, 8168 up to 8168b (included) and 8101
2. {8102e, 8168c} and beyond
- notwithstanding the "first descriptor" and "last descriptor" bits, the
same Tx descriptor content is enforced when a packet consists of several
descriptors. The chipsets are documented to require it.
