Ok to recap I have nforce 430 MCP13 I checked the src and current and 6.2-stable driver I am using are the same version number but my driver src has this added above tunables. /* definitions for backporting RELENG-6 */ #ifndef IFCAP_TSO4 #define IFCAP_TSO4 0 #define CSUM_TSO 0 #endif #ifndef VLAN_CAPABILITIES #define VLAN_CAPABILITIES(x) #endif #ifndef IFCAP_VLAN_HWCSUM #define IFCAP_VLAN_HWCSUM 0 #endif I am guessing If I set the values to 1 I get the features but would like someone to confirm this for me before I try it thanks. I only have remote access so if it stops the card working I lose access to the box.
