Johnathan Corgan f32bc83034 docs: correct Ethernet MTU framing rustdoc
The Ethernet data frame format is `[type:1][length:2 LE][payload]`,
so the per-link payload MTU is the interface MTU minus 3 bytes,
not minus 1. The 2-byte length field is required to trim NIC
minimum-frame padding before AEAD verification.

The implementation in src/transport/ethernet/mod.rs already uses
saturating_sub(3) correctly; only the rustdoc on the effective_mtu
field and the EthernetConfig.mtu field's documentation lagged behind.

No behaviour change.
