We have a Snort sensor that is running on a 10g Silicom card using DNA/Libzero. 
 I see in the snortd init script it makes a number of changes to the NIC using 
ethtool.  Are these the settings that I should be using for this scenario?

  ethtool -C $1 rx-usecs 1000 &>/dev/null
  ethtool -K $1 tso off &>/dev/null
  ethtool -K $1 gro off &>/dev/null
  ethtool -K $1 lro off &>/dev/null     #may not be supported
  ethtool -K $1 gso off &>/dev/null
  ethtool -K $1 rx off   &>/dev/null
  ethtool -K $1 tx off   &>/dev/null
 ethtool -G $1 tx 32768 &>/dev/null
  ethtool -G $1 rx 32768 &>/dev/null
  ethtool -K $1 sg off  &>/dev/null

Thx.

Craig
