Hello, Marius. You wrote 13 =FF=ED=E2=E0=F0=FF 2011 =E3., 1:59:07: > Note that even the RealTek supplied driver always triggers an > auto-negotiation when manually setting the media though.

One think I'm sure, that "mii-tool" on Linux helps now, and "ifconfig media / mediaopt" doesn't (without this patch & turned on option), so it seems, that Linux turn autonegotiation off when media is set manually. And, yes, without manual setting media (with autonegatiotion) Linux has same problem -- half/full duplex mismatch. > Unfortunately, I didn't get to checking whether the MAC versions > in question are amongst the ones that get patched so far. > In any case I don't think we can easily change this (default) > behavior after such a relatively long time as it would break POLA > for an unknown number of users, even if it probably shouldn't have > been made the default in the first place (but again on the other It is why I do option in such way, that old users, for whom current implementation works, doesn't notice any difference -- rgephy works exactly the same way as usual untill you set option. And, yes, I think, that additional media option will be better, but it looks like major feature and not small patch :) --=20 // Black Lion AKA Lev Serebryakov <lev@serebryakov.spb.ru>
