Increase default netdev_max_backlog to 10x
It has been observed that on large clouds the netdev backlog
buffer might overflow. This change increases the default by ten
times.
The /proc/net/softnet_stat file contains a counter in the 2nd
column that is incremented when the netdev backlog queue overflows.
If this value is incrementing over time, then netdev_max_backlog
needs to be increased [1].
