This structure contains the IPv4 filter type of service
- Parameters
-
| val | Type of service value |
| mask | Packet matches the TOS filter if: (IPv4_filter_tos_val and IPv4_filter_tos_mask) == (TOS value in the IP packet & IPv4_filter_tos_mask) Example:
- IPv4_filter_tos_val = 00101000
- IPv4_filter_tos_mask = 11111100 The filter will compare only the first 6 bits in the IPv4_filter_type_of_service with the first 6 bits in the TOS field of the IP packet. The first 6 bits in the TOS field of the IP packet must be 001010 to match the filter. The last 2 bits can be anything since they are ignored by filtering.
