28 * DOC: IPA Filter and Route Tables
30 * The IPA has tables defined in its local (IPA-resident) memory that define
38 * by all IPA hardware (IPA v4.2 doesn't support hashed tables).
41 * an object (such as a route or filter table) in IPA-resident memory must
59 * for endpoint 2, and so on. Space is set aside in IPA local memory to
66 * IPA filtering functionality.
68 * IPA Filter Table
87 * though the AP currently does not use the IPA routing functionality.
89 * IPA Route Table
