K 10 svn:author V 7 yongari K 8 svn:date V 27 2008-08-09T02:11:59.766787Z K 7 svn:log V 480 MFC r181271. Don't enable TSO by default. Users of RTL8169/8110 reported watchdog timeout issues and the root cause seems to stem from silicon bug of controller. Personally I couldn't reproduce it on RTL8169 controller but it seems it's dependent on usage pattern. For newer PCIe based controllers I have no TSO complaints but turning off TSO would be more safe. Users who are sure that their controller works with TSO can still reenable the TSO with ifconfig(8).
