RE: [PATCH for-7.2] rtl8139: honor large send MSS value

[Tobias Fiebig]

Heho,
I gave v3 a shot and it performs as expected; For a requested MSS of 1320, TSO 
consistently uses a 1308 MSS. So for me, this patch works. Thanks for fixing 
this. :-)

Sadly, I do not have boxes to test with .1q around; If none of you has either, 
and that should be tested as well, I can give it a shot in the coming days, but 
it might take some time.

Side note: I found the 'missing' 12b in 12b of TCP options being added. :-| So 
sorry for that noise.

With best regards,
Tobias
