}

A single learn specification.

Learn specs define how to construct match fields and actions in the learned flow.

MatchImmediate

Match: use immediate value

Fields

dst_field: u32

Destination field

value: Vec<u8>

Value to match

n_bits: u16

Number of bits

LoadField

Action: copy field from packet to action’s field

Fields
