Action for UFDB entry.
- `dst-drop` - packets are dropped when their destination MAC matches the entry.
- `dst-redirect-to-cpu` - packets are redirected to the CPU when their destination MAC matches the entry.
- `forward` - packets are forwarded.
- `src-and-dst-drop` - packets are dropped when their source MAC or destination MAC matches the entry.
- `src-and-dst-redirect-to-cpu` - packets are redirected to CPU when their source MAC or destination MAC matches the entry.
- `src-drop` - packets are dropped when their source MAC matches the entry.
- `src-redirect-to-cpu` - packets are redirected to the CPU when their source MAC matches the entry.
