Sets the DSCP field.

pub fn set_ecn(&mut self, ecn: u8)

Sets the ECN field.

pub fn set_total_length(&mut self, total_length: u16)

Sets the total length field.

pub fn set_id(&mut self, identification: u16)

Sets the identification field.

Sets the flags field.

pub fn set_fragment_offset(&mut self, fragment_offset: u16)

Sets the fragment offset field.

pub fn set_ttl(&mut self, ttl: u8)

Sets the TTL field.

pub fn set_protocol(&mut self, protocol: u8)

Sets the protocol field.

pub fn set_src_ip(&mut self, src_ip: &[u8; 4])

Sets the source IP address field.
