- | ====Enabling Tx abdicate (iflib drivers) | + | ===== Results |
- | + | ||
- | Second, if NIC drivers is iflib based you should enable TX abdicate (automatically done with BSDRP but not on a generic FreeBSD): | + | |

- | ==== Disabling ICMP redirect === | + | |
- | + | ||
- | ICMP redirect is enabled by default on a generic FreeBSD (it's disabled by default on BSDRP), and this feature disable the fast tryforward code path. | + | |
