Heho,
Quick follow-up; Applied the change you suggested, but there are still some
things to test.
While this now works (mostly), MSS values are still off; Especially the
behavior below <=1036 is difficult, as for v4 the minimum MTU is 576 and
minimum MSS is 536:
Requested DPRINT
1320 1292
1319 1291
1100 1024
1036 1024
1035 271
1000 268
So, I guess there is something else amiss; Will test more in-depth later
tonight and shift the bits a bit; Also, I will look into behavior when forcing
>1500 MTUs (in case that works with the rtl8139).
Sidenote: This all seems to be a non-issue for v6, as the RTL8139 does not
support TSO for v6, so at least one thing less to worry about. ;-)
With best regards,
Tobias
