ixgbe sysctl hardware defaults

Browse Source 
Added hw.ix.flow_control which enables the default flow_control of all ix
interfaces to be set in loader.conf.

Added hw.ix.advertise_speed which enables the default advertised_speed of
all ix interfaces to be set in loader.conf.

Made enable_aim device independent based on hw.ix.enable_aim default.
