[Click] Still unable to find the handler on NIC packet losses

[Brecht Vermeulen]

Hi,

are you using the e1000 drivers ?
Then you have additional information in /proc/PRO_LAN_Adapters

Maybe you can give more information on where you heard/read/saw about 
those handlers, and which cards you are using ?

regards,
Brecht
