Adding Flow Director sysctls to ixgbe(4) (was: netmap: traffic distribution)

[Takuya ASADA]

Hi,

This is updated version of the patch.
Signature filter list feature is added.

Here're usage of ixgbetool:
- add a filter
ixgbetool ix0 add_sig_filter tcpv4 10.1.0.1 34763 10.1.0.2 22 3
- show filters
ixgbetool ix0 show_sig_filter
- del a filter
ixgbetool ix0 del_sig_filter 1
