T3 Filtering configuration
T3 Filtering options can be set only when offload driver (t3_tom) is not loaded.
This module lists various parameters which can be set while determining filtering options for a
system IP. You can set the maximum number of filters and also add/delete filters. A filter with
default values (the Action field set to pass; the Protocol field set to any) is created at the time
of configuring the filtering module. To remove the default filter, enter 0 in the Set Maximum
Filters field and click on Set Filters. The fields lfName and FilterId are mandatory. The Action
field is set to pass and the Protocol field is set to any by default. Other possible values for the
Protocol field are tcp, udp and frag. The Priority field can be used to determine the priority of
a filter when Vlan ids are same. Insert at position features allows user to add a filter at a
specified position.
