Hi all...
in struct net_device_stats all members are defined as unsgined long. In
time of gigabit ethernet this takes not long to overflow. Are there any
plans to change these coutners to unsigned long long? I saw in ifconfig
source code the byte and packet counters are already defined as unsigned
long long.
I've tried the attached little patch which seems to work well. Are there
any good reasons against this changes?
