Constant DHCP_OPTIONS_BUF_SIZE 

pub const DHCP_OPTIONS_BUF_SIZE: usize = raw::DHCP_OPTIONS_BUF_SIZE; // 128usize

Size of the raw options buffer in a DHCP lease, in bytes.

Only used with the dhcpv4-options feature, which keeps the options of a lease that the client itself does not parse. Options past this many bytes are dropped.

This is a limit with and without alloc. Default: 128.
