 uint8\_t **option\_type**\
 uint8\_t **option\_len**\
 uint8\_t **match\_on\_class\_mode**\
 uint8\_t **offset**\

Definition at line **283** of file **rte\_pmd\_mlx5.h**.

## Field Documentation

### rte\_be16\_t option\_class

The class of the GENEVE TLV option. Relevant only when 'match\_on\_class\_mode' is 1.

Definition at line **288** of file **rte\_pmd\_mlx5.h**.

### uint8\_t option\_type

The type of the GENEVE TLV option. This field is the identifier of the option.

Definition at line **293** of file **rte\_pmd\_mlx5.h**.

### uint8\_t option\_len

The length of the GENEVE TLV option data excluding the option header in DW granularity.

Definition at line **298** of file **rte\_pmd\_mlx5.h**.

### uint8\_t match\_on\_class\_mode

Indicator about class field role in this option: 0 - class is ignored. 1 - class is fixed (the class defines the option along with the type). 2 - class matching per flow.

Definition at line **305** of file **rte\_pmd\_mlx5.h**.

### uint8\_t offset

The offset of the first sample in DW granularity. This offset is relative to first of option data. The 'match\_data\_mask' corresponds to option data since this offset.

Definition at line **311** of file **rte\_pmd\_mlx5.h**.

### uint8\_t sample\_len

The number of DW to sample. This field describes the length of 'match\_data\_mask' in DW granularity.

Definition at line **317** of file **rte\_pmd\_mlx5.h**.

### rte\_be32\_t\* match\_data\_mask

Array of DWs which each bit marks if this bit should be sampled. Each nonzero DW consumes one DW from maximum 7 DW in total.

Definition at line **322** of file **rte\_pmd\_mlx5.h**.
