No, sorry - I'm just the messenger here and moved everything to 6.9 already. Cc'ing Jakub and Eric. My understanding is that the previous commit was a performance enhancement, so if this turns out to be too difficult then maybe 378979e94e95 ("tcp: remove 64 KByte limit for initial tp->rcv_wnd value") should just not be merged either. I have both patches on 6.9 but really cannot say whether they should go to older releases. Let's wait for Jakub or Eric. cheers Holger
